How to Conduct a Cardiovascular Assessment

01 · Definition

What is a cardiovascular assessment, and what does it include?

A cardiovascular assessment is a systematic evaluation of the heart and blood vessels that combines a focused history with physical examination of the heart and peripheral vascular system. It is one of the most frequently performed assessments in nursing and medicine, used both as part of a routine full-body exam and as a targeted response to a specific complaint, chest pain, shortness of breath, palpitations, swelling, or fainting, that points toward the heart.

The physical examination portion draws on three of the four classic examination techniques: inspection, palpation, and auscultation. The fourth, percussion, historically used to estimate the heart’s size and borders by tapping the chest wall and listening for changes in resonance, has a much smaller role in the modern cardiac exam than it does in, say, the abdominal or respiratory exam; chest imaging and echocardiography now do that job more reliably, and percussion is largely retained in cardiac teaching as background context rather than an active technique.

The four components in practice

In sequence, a full assessment moves through: a history covering symptoms and cardiac risk factors; general inspection of the patient’s color, breathing, and visible chest and extremity findings; palpation of the peripheral pulses and the precordium, the area of the chest overlying the heart; and auscultation of the heart at five standard sites, along with the carotid arteries and, when indicated, the abdomen and extremities for bruits. Blood pressure and pulse measurement, though sometimes treated as a separate “vital signs” step, are really part of this same sequence and are covered here alongside it.

Who performs this assessment, and where

Nurses, nurse practitioners, physicians, physician assistants, and paramedics all perform versions of this exam, and the depth varies by setting: a triage nurse might focus on vital signs, general appearance, and peripheral perfusion, while a full admission assessment or a cardiology consult works through every site and maneuver described in this guide. The sequence below reflects the fuller version, with notes throughout on which pieces are commonly abbreviated in faster-paced settings.

02 · History

Taking the history before you touch the patient

A cardiovascular history isn’t a formality before the “real” exam; it’s what tells you which parts of the physical exam to spend the most time on. A patient reporting exertional chest pressure and a patient reporting ankle swelling warrant a physical exam that shares a common structure but a very different emphasis, and the history is what makes that judgment possible.

For any cardiac symptom, a structured framework, commonly taught using a mnemonic such as OLDCARTS, onset, location, duration, character, aggravating and alleviating factors, radiation, timing, and severity, helps ensure nothing important gets skipped. Applied to chest pain specifically, this means asking not just whether it hurts, but when it started, what brings it on or relieves it, whether it radiates to the arm, jaw, or back, and how it compares to any prior episodes the patient has had.

The core symptoms to screen for

Beyond chest pain, a cardiovascular history should specifically ask about dyspnea, and whether it occurs at rest, with exertion, or when lying flat, orthopnea, or wakes the patient from sleep, paroxysmal nocturnal dyspnea; palpitations and whether they feel regular or irregular; syncope or near-syncope; lower extremity edema; unusual fatigue; and claudication, pain in the legs brought on by walking and relieved by rest, which points toward peripheral arterial disease rather than the heart itself.

Risk factors and history round out the picture

A complete history also covers modifiable risk factors, hypertension, diabetes, dyslipidemia, smoking, obesity, and inactivity, along with family history of premature coronary disease, typically defined as onset before age 55 in a male first-degree relative or 65 in a female one. Past cardiac history, prior heart attack, cardiac surgery, stents, arrhythmias, and current medications, particularly anticoagulants, antihypertensives, and diuretics, all shape both what you expect to find on exam and how you interpret it once you do.

03 · Inspection

General inspection: what to observe first

Inspection starts before you touch the patient, often before you’ve finished the history, and it’s easy to skip past because it doesn’t feel like a discrete “step.” Slowing down here catches findings that are easy to miss once you’re focused on a stethoscope or a blood pressure cuff.

Start broad: does the patient look comfortable, or are they in distress, working hard to breathe, diaphoretic, clutching their chest? Note skin color, pallor, cyanosis, either central (lips, tongue) or peripheral (fingertips, nail beds), and whether the patient appears their stated age or older, which can itself be a subtle marker of chronic illness. Note the chest wall for surgical scars, a midline sternotomy scar signals prior open-heart surgery, and for the small, firm outline of a pacemaker or implantable defibrillator, usually just below one clavicle.

Findings specific to cardiovascular disease

A few inspection findings point fairly specifically toward cardiac or vascular pathology. Clubbing of the fingernails, a loss of the normal angle where the nail meets the finger, suggests chronic hypoxia and is associated with certain congenital heart defects and long-standing lung disease. Xanthelasma, yellowish, slightly raised deposits around the eyelids, reflects lipid deposition and correlates with hyperlipidemia. Visibly distended neck veins, obvious without the formal jugular venous pressure technique described later, suggest significantly elevated central venous pressure. In the extremities, look for varicosities, chronic skin changes from venous insufficiency, hair loss, and any visible pulsations on the chest wall itself, which in a thin patient can sometimes reveal an abnormally forceful or displaced heartbeat before you’ve palpated anything.

04 · Vitals & BP

Blood pressure and pulse: technique and classification

Blood pressure is one of the most frequently measured numbers in medicine and, because of exactly that familiarity, one of the most frequently measured incorrectly. Cuff size, patient position, arm support, and even conversation during the reading all measurably shift the result, which is part of why the current guideline puts as much emphasis on measurement technique as on the resulting numbers.

Correct technique means a cuff whose bladder covers roughly 80 percent of the arm’s circumference, the patient seated with their back supported, feet flat on the floor, arm at heart level, and at least five minutes of rest beforehand with no talking, caffeine, or smoking in the prior 30 minutes. Blood pressure should be checked in both arms at least once, since a difference greater than about 10 to 15 mmHg between arms can point toward subclavian artery narrowing or, in the right clinical context, aortic dissection. Manual measurement relies on Korotkoff sounds: a first tapping sound marking systolic pressure, a period of softer swishing, a return to crisper tapping, muffling, and finally silence, which marks diastolic pressure in most adults.

Current classification and what changed in 2025

The 2025 ACC/AHA blood pressure guideline replaced the 2017 version that most clinicians trained under, and it keeps the same four numeric categories: normal, under 120 systolic and under 80 diastolic; elevated, 120 to 129 systolic and under 80 diastolic; stage 1 hypertension, 130 to 139 systolic or 80 to 89 diastolic; and stage 2 hypertension, 140 or higher systolic or 90 or higher diastolic. What changed is less about the numbers and more about method: the new guideline reasonably favors automated oscillometric devices over manual auscultation for in-office readings, leans more heavily on out-of-office confirmation through home or ambulatory monitoring, and explicitly cautions against relying on unvalidated cuffless devices, including smartwatches, for diagnosis. Markedly elevated readings, well above the stage 2 threshold and accompanied by symptoms, remain a reason for prompt reassessment and escalation regardless of which specific category label is used.

Pulse: rate, rhythm, and what a deficit means

A normal adult resting heart rate falls between 60 and 100 beats per minute, though well-conditioned athletes often run lower without any pathology. Beyond the rate, note the rhythm: is it regular, or irregularly irregular, which raises suspicion for atrial fibrillation? When an irregular rhythm is suspected, comparing the radial pulse rate to the apical rate, counted by auscultation over the mitral area, for a full minute can reveal a pulse deficit, apical beats that aren’t strong enough to reach the wrist as a palpable pulse, which is common in atrial fibrillation and worth documenting explicitly rather than reporting a single averaged number.

05 · Peripheral pulses

Palpating the peripheral pulses

Peripheral pulses are checked at seven standard sites: carotid, brachial, radial, femoral, popliteal, posterior tibial, and dorsalis pedis. Each tells you something slightly different about the vascular tree between the heart and that point, and comparing sides is often more informative than any single reading on its own.

Use the pads of your first two or three fingers rather than your thumb, since the thumb carries a faint pulse of its own that can be mistaken for the patient’s. Carotid pulses should always be palpated one side at a time, gently, never simultaneously; compressing both carotids at once can meaningfully reduce blood flow to the brain, and firm carotid pressure can also trigger a vagal response that slows the heart rate. Elsewhere, bilateral comparison is not just safe but genuinely useful: pulses should be symmetric in strength and timing, and a delay or difference between, say, the right and left radial pulses, or between the radial and femoral pulses on the same side, can point toward vascular narrowing, including congenital coarctation of the aorta when a radial-femoral delay is found in a younger patient.

Grading pulse strength

Most institutions grade pulse strength on a scale from 0 to either 3+ or 4+: 0 for absent, 1+ for diminished or weak, 2+ for normal, and 3+, or 3+ and 4+ where a four-point scale is used, for increased or bounding. Exactly where the top of that scale sits varies by institution, which is one of the small but genuine inconsistencies in physical exam documentation worth knowing about rather than assuming is standardized nationally.

06 · JVP

Assessing jugular venous pressure

Jugular venous pressure, often abbreviated JVP, is a bedside estimate of central venous and right atrial pressure, and it’s widely considered one of the harder physical exam skills to learn well, largely because it depends on distinguishing a pulsation that isn’t palpable from a nearby pulse that is.

Position the patient reclined at roughly 30 to 45 degrees with the head turned slightly to the side opposite the one being examined, and use a light source directed tangentially across the neck, which makes subtle pulsations far easier to see than direct overhead lighting does. The internal jugular vein’s pulsation is distinguished from the nearby carotid pulse by several features: it isn’t palpable, it typically shows a double flicker per cardiac cycle rather than the carotid’s single sharp upstroke, its height changes visibly with the patient’s position and with respiration, and it’s easily obliterated by light finger pressure at the base of the neck, none of which is true of the carotid.

Turning the pulsation into a number

Once the pulsation is identified, measure the vertical distance from the sternal angle, the bony ridge where the second rib meets the sternum, up to the top of the visible pulsation. Because the sternal angle sits roughly 5 centimeters above the right atrium in most positions, adding that constant to the measured height gives an estimated central venous pressure in cm H2O. Reference ranges vary slightly by source, but a normal mean value is commonly cited as roughly 6 to 8 cm H2O; a level below about 5 cm H2O can suggest hypovolemia, while a level above roughly 9 cm H2O is considered elevated and raises concern for right heart failure, volume overload, tricuspid valve disease, constrictive pericarditis, or, when the elevation is non-pulsatile, superior vena cava obstruction.

Hepatojugular reflux

The hepatojugular, or abdominojugular, reflux test adds useful information when the JVP is borderline. With the patient breathing normally through an open mouth, apply firm, sustained pressure over the right upper quadrant for roughly 10 to 15 seconds while watching the neck. A sustained rise in JVP of about 3 to 4 cm or more that persists throughout the compression, rather than a brief bump that fades, is considered a positive test and supports a diagnosis of right-sided heart failure or otherwise elevated cardiac filling pressures.

07 · Palpation

Palpating the precordium

The precordium is the area of the chest wall overlying the heart, and palpating it is how you locate and characterize the point of maximal impulse, or PMI, along with any abnormal vibrations or sustained movements that auscultation alone would miss.

The PMI, sometimes called the apical impulse, is normally found at the fifth intercostal space in the midclavicular line, felt as a brief, localized tap roughly the size of a quarter, about 2 to 3 centimeters across. A PMI that is displaced laterally or downward, enlarged, or sustained rather than brief suggests left ventricular enlargement or hypertrophy, and is a finding worth specifically documenting rather than noting only that “heart sounds were auscultated.”

Heaves, lifts, and thrills

Beyond the PMI, palpate broadly across the precordium with the palm and then the fingertips for heaves or lifts, a sustained, forceful outward movement of the chest wall, most often felt along the lower left sternal border and suggesting right ventricular hypertrophy, and for thrills, a palpable vibration that corresponds to a loud murmur, generally grade IV or above on the scale described later. Thrills are usually easiest to feel with the flat of the fingers or the metacarpophalangeal joints placed lightly over the same five areas used for auscultation.

08 · Auscultation

The auscultation sites, and how to listen

Cardiac auscultation uses five standard chest wall locations, and it’s worth being explicit about a detail that trips up a lot of learners: these sites are not directly over the anatomic valves themselves. They’re the points on the chest wall where sound generated by each valve travels most clearly through the blood and tissue, which is why they sit some distance from the valve’s actual anatomic position.

The aortic area sits at the second right intercostal space, right sternal border. The pulmonic area mirrors it on the left, second left intercostal space. Moving down one space to the third left intercostal space reaches Erb’s point, named for the 19th-century German neurologist Wilhelm Erb rather than any cardiologist, a detail that surprises most people who learn it. Erb’s point is a useful general listening spot where both aortic- and pulmonic-origin sounds are often heard clearly, and it’s frequently the best place to hear the soft, high-pitched diastolic murmur of aortic regurgitation. Continuing down, the tricuspid area sits at the fourth left intercostal space, lower left sternal border, and the mitral, or apical, area sits at the fifth left intercostal space in the midclavicular line, the same location as the PMI.

Diaphragm, bell, and sequence

The stethoscope’s diaphragm, pressed firmly against the skin, transmits higher-pitched sounds well, S1, S2, and most murmurs. The bell, held with only light contact, is better for the low-pitched sounds, an S3 or S4 gallop, or the diastolic rumble of mitral stenosis. Both should be used at each of the five sites. Sequence matters less than completeness, and teaching varies here: some educators recommend starting at the aortic area and working down toward the apex, base to apex, while others, following early recommendations from cardiologists Levine and Harvey, teach starting at the apex and working up toward the base. Either sequence works as long as all five sites are covered systematically, in more than one patient position when possible, since the left lateral decubitus position brings out a soft S3 or the murmur of mitral stenosis, and sitting forward with the breath held in exhalation brings out the murmur of aortic regurgitation.

09 · Heart sounds

Identifying S1, S2, and extra heart sounds

The familiar “lub-dub” of a heartbeat is S1 and S2, and everything else you might hear, an added sound, a murmur, a rub, is defined relative to those two reference points. Learning to place S1 and S2 confidently is what makes the rest of auscultation possible.

S1 marks the closure of the mitral and tricuspid valves and the start of systole; it’s loudest at the apex. S2 marks the closure of the aortic and pulmonic valves and the start of diastole; it’s loudest at the base, the aortic and pulmonic areas. S2 normally splits into two audible components, aortic closure followed very slightly by pulmonic closure, and that split widens on inspiration as increased venous return to the right heart briefly delays pulmonic valve closure. This physiologic splitting is a normal finding, most easily heard in younger patients at the pulmonic area, and shouldn’t be mistaken for an abnormal extra sound.

S3 and S4: the gallops

S3, sometimes called a ventricular gallop, is a low-pitched sound occurring early in diastole, best heard with the bell at the apex, with the patient in the left lateral decubitus position. It can be a normal finding in children, young adults, and pregnancy, but in an older adult it’s typically a sign of volume overload or reduced ventricular compliance, and is a classic finding in decompensated heart failure. S4, an atrial gallop, occurs late in diastole, just before the next S1, and reflects blood being forced into a stiff, poorly compliant ventricle by atrial contraction; it’s associated with long-standing hypertension and left ventricular hypertrophy, and, unlike a physiologic S3, an S4 is essentially never a normal finding in adults.

10 · Murmurs

Recognizing and grading murmurs

A murmur is the audible result of turbulent blood flow, whether from a narrowed valve, a leaking one, or simply a high-output state like fever, anemia, or pregnancy that speeds blood through a normal valve. Characterizing one well means describing several separate qualities together, not just noting that a murmur is present.

Start with timing: does the murmur fall between S1 and S2 (systolic) or between S2 and the next S1 (diastolic)? Then note where it’s loudest, whether and where it radiates, aortic stenosis classically radiates toward the carotids, mitral regurgitation toward the axilla, its pitch and quality (blowing, harsh, rumbling), and how it responds to maneuvers such as the Valsalva maneuver, standing, squatting, or sustained handgrip, which shift preload and afterload in ways that can help distinguish one cause from another.

The Levine scale

Systolic murmurs are graded on the Levine scale, developed by cardiologist Samuel A. Levine and still the standard reference nearly a century later, running from grade I, audible only after listening carefully for several cycles, through grade VI, loud enough to hear with the stethoscope lifted entirely off the chest. A palpable thrill defines grade IV and above. Grades I and II are often innocent; grades III and above are more often, though not always, associated with structurally significant valve disease. Diastolic murmurs are conventionally graded on a separate, simpler 1-to-4 scale, and, unlike systolic murmurs, are generally regarded as clinically significant regardless of how faint they are, a distinction that current cardiology literature notes is still commonly applied incorrectly in practice.

Innocent murmurs are common, not rare

Soft, early systolic murmurs with no radiation and normal S1 and S2 are common findings in children and in adults during high-output states, and are not, by themselves, evidence of structural heart disease. The distinction between an innocent murmur and one that warrants further workup rests on the combination of grade, timing, associated symptoms, and other exam findings, not on the presence of a murmur alone.

11 · Vascular exam

The peripheral vascular exam

A cardiovascular assessment extends past the chest. Skin, temperature, edema, and capillary refill in the extremities all reflect how well blood is actually reaching the periphery, and several of these checks are quick enough to include in nearly any exam.

Assess skin color, temperature, and texture, cool, pale skin suggests reduced arterial perfusion, while warm, well-perfused skin is reassuring, and note hair distribution on the lower legs, since chronic arterial insufficiency often causes hair loss over the affected area. Look for ulcers and note their location and appearance: arterial ulcers typically occur over pressure points such as the toes or lateral malleolus and are painful, while venous ulcers cluster around the medial malleolus and are often less painful relative to their size.

Edema

Peripheral edema is typically graded on a 1+ to 4+ pitting scale based on the depth of the indentation left by firm fingertip pressure and how quickly it rebounds, though the exact depth-to-grade correspondence varies somewhat between institutions and textbooks, so, as with pulse grading, it’s worth confirming local convention. It’s also worth distinguishing pitting edema, which indents and slowly refills, from non-pitting edema, seen in conditions like lymphedema or the myxedema of hypothyroidism, which does not indent in the same way and points toward a different underlying cause entirely.

Capillary refill time

To check capillary refill, press the pad of a fingertip or toe until it blanches, hold for several seconds, release, and count how long color takes to return. The figure most commonly taught, under 2 seconds, is more of a convention than a precisely evidence-based cutoff; it traces back to a threshold picked somewhat arbitrarily in the 1980s, and more recent research examining refill at the finger pulp specifically has supported a 3-second cutoff as a more reliable normal range. Refill can also normally run longer, up to roughly 4 to 4.5 seconds, in older adults, and is meaningfully slowed by a cold room or cold extremity, both worth accounting for before calling a result abnormal.

12 · Special tests

Special maneuvers: orthostatics, Allen’s test, and ABI

A few additional maneuvers aren’t part of every cardiovascular assessment but are essential in specific situations: evaluating unexplained dizziness on standing, confirming safe access before a radial arterial line, or screening for peripheral arterial disease.

13 · Documentation

Documenting findings and escalating red flags

A finding that isn’t documented clearly is close to a finding that wasn’t made at all, since the next clinician has no way to compare it against a baseline. Precise, standardized documentation is what turns a physical exam from a private impression into something the rest of the care team can actually use.

Favor specific, quantified language over general impressions: “PMI at the 5th intercostal space, midclavicular line, non-displaced” communicates far more than “heart sounds normal.” Note the patient’s position during the exam, particularly for JVP and for any murmur, since both can look meaningfully different supine, reclined, or sitting forward, and use the standardized grading scales described throughout this guide, pulse 0 to 4+, edema 1+ to 4+, murmurs on the Levine scale, rather than vaguer terms like “strong” or “loud” that don’t translate cleanly between examiners.

Findings that warrant immediate escalation

Certain findings should prompt urgent reassessment or escalation rather than routine documentation: new or worsening chest pain, especially with hemodynamic instability; a new murmur accompanied by signs of heart failure; the combination of elevated JVP, hypotension, and muffled heart sounds, classically known as Beck’s triad and associated with cardiac tamponade; a significant, new asymmetry between pulses, which can signal aortic dissection; and, in the extremities, the “6 P’s” of acute limb ischemia, pain, pallor, pulselessness, paresthesia, paralysis, and poikilothermia, meaning the limb feels cold. Any of these findings changes an assessment from routine documentation to a time-sensitive clinical event.

14 · Consensus

Where does clinical guidance broadly agree?

Physical examination has always had more art to it than a lab value does, but a solid core of this assessment is standardized across nursing curricula, medical training, and published guidelines, not a matter of individual style.

There’s broad agreement on the five auscultation landmarks and their approximate anatomic locations, on the Levine scale as the reference standard for grading systolic murmur intensity, and on the current four-category blood pressure classification reaffirmed in the 2025 ACC/AHA guideline. There’s broad agreement that measurement technique, cuff size, patient position, arm support, rest before the reading, meaningfully affects the accuracy of a blood pressure result, which is part of why the newest guideline devotes so much attention to standardizing it. There’s broad agreement that JVP and hepatojugular reflux remain genuinely useful, teachable bedside skills for estimating volume status, even as the debate below covers how they compare to newer tools. And there’s broad agreement, reflected consistently across the sources in this guide, that history and physical exam findings are meant to be interpreted together and against each other, not read in isolation as if any single finding could confirm or rule out a diagnosis on its own.

15 · Debate

Where does practice and evidence still vary?

A few areas of this exam are genuinely unsettled, either because the evidence behind a long-taught technique turns out to be thinner than assumed, or because newer tools are changing what “the physical exam” even means at the bedside.

Physical exam reliability, examiner to examiner

Studies of inter-rater reliability, different clinicians examining the same patient, have found real variability in some components of this exam, murmur detection and JVP estimation among them. That variability is one of the arguments cited by clinicians who favor supplementing, or in some cases substituting, certain elements of the traditional exam with point-of-care ultrasound, for instance using an ultrasound view of the inferior vena cava to estimate volume status rather than relying on JVP alone. This is a live, ongoing discussion in medical education, not a settled question, and different training programs currently land in different places on how much weight to put on each approach.

Capillary refill’s “2-second rule” is more contested than it’s taught

As noted above, the traditional 2-second capillary refill cutoff has a surprisingly informal origin, and more recent evidence pushes toward a 3-second threshold, measured at the finger pulp specifically, as more defensible. Many clinical teaching materials haven’t caught up to that shift, so it’s common to see the older 2-second figure and the newer 3-second figure used side by side without explanation.

Homans’ sign persists in teaching despite being discouraged

Homans’ sign, calf pain on forced dorsiflexion of the foot, is widely flagged in current literature as unreliable for diagnosing deep vein thrombosis, with reported sensitivity as low as 10 to 54 percent and specificity from 39 to 89 percent, alongside a theoretical risk that the maneuver itself could dislodge a clot. Despite that, it’s still referenced in some nursing and medical curricula, partly, by most accounts, because it’s an easy technique to demonstrate and remember. Current practice favors structured tools like the Wells score combined with D-dimer testing or ultrasound rather than any single physical sign.

16 · Quick reference

Grading scales and normal ranges at a glance

Because this guide spans several separate grading conventions, a single reference view of the normal ranges and scales covered above is useful for keeping the numbers straight.

• Blood pressure

  Normal <120/<80; elevated 120–129/<80; stage 1, 130–139 or 80–89; stage 2, ≥140 or ≥90 mmHg (2025 ACC/AHA).

• Resting heart rate

  60 to 100 beats per minute in a typical adult at rest.

• Peripheral pulses

  Graded 0 (absent) to 3+ or 4+ (bounding), depending on institutional convention; 2+ is normal.

• Jugular venous pressure

  Normal mean approximately 6–8 cm H2O; <5 suggests hypovolemia; >9 is elevated.

• Point of maximal impulse

  5th intercostal space, midclavicular line; brief tap, about 2–3 cm across.

• Systolic murmurs (Levine scale)

  Grade I (faint) to VI (audible off the chest); thrill present from grade IV up.

• Diastolic murmurs

  Graded 1 to 4; generally treated as pathological at any grade.

• Peripheral edema

  Graded 1+ to 4+ by pit depth and rebound time; conventions vary by institution.

• Capillary refill time

  Commonly taught as <2 seconds; evidence supports up to 3 seconds at the finger pulp, longer in older adults.

• Orthostatic hypotension

  ≥20 mmHg drop in systolic or ≥10 mmHg drop in diastolic pressure within 3 minutes of standing.

• Ankle-brachial index

  Normal approximately 0.90–1.30; ≤0.90 suggests PAD; >1.30 suggests non-compressible vessels.

17 · Common errors

Common misconceptions, addressed directly

A handful of specific misunderstandings about this exam recur across training settings. Naming them directly clears up most of the confusion.

“Auscultation sites sit directly over their named valve”

They don’t. The aortic, pulmonic, tricuspid, and mitral areas are the points on the chest wall where sound from each valve is best transmitted through blood and tissue, not the valve’s actual anatomic location.

“A murmur always means heart disease”

Soft, early systolic murmurs with no radiation are common and often innocent, particularly in children and during high-output states like fever, pregnancy, or anemia. Grade, timing, and associated findings matter far more than the simple presence of a murmur.

“Homans’ sign is a reliable way to confirm or rule out a DVT”

It isn’t. Its sensitivity and specificity are both too inconsistent to rely on alone, and current practice favors structured clinical prediction tools combined with objective testing.

“You can save time by checking both carotid pulses at once”

This isn’t a shortcut worth taking. Simultaneous bilateral carotid compression can meaningfully reduce cerebral blood flow; palpate one side at a time.

“Percussion is a routine, essential part of the cardiac exam”

It was, historically, but modern practice relies on imaging to assess heart size and borders, and percussion now plays a minor role in most current cardiac exam teaching compared with inspection, palpation, and auscultation.

18 · Outlook

Where cardiovascular assessment is heading

The core sequence described in this guide has changed remarkably little in decades, but the tools surrounding it are shifting, and training programs are actively working out how the traditional bedside exam and newer technology should fit together rather than compete.

Point-of-care ultrasound is the most visible change. Handheld and pocket-sized ultrasound devices are increasingly used alongside, and sometimes instead of, specific elements of the physical exam, most notably using an ultrasound view of the inferior vena cava as a more directly visualized alternative to estimating volume status from JVP alone. Digital and “smart” stethoscopes that record, amplify, and in some cases algorithmically flag murmurs or arrhythmias are moving from novelty into mainstream clinical use, particularly in primary care and telehealth settings where a specialist isn’t in the room.

What technology hasn’t replaced

Telehealth has also exposed a real limit: history-taking and visual inspection translate reasonably well to a video visit, but palpation and auscultation, in any traditional sense, do not, which has driven interest in patient-side digital stethoscope peripherals and remote patient-monitoring wearables that track heart rate, rhythm, and blood pressure between visits. None of this has displaced the underlying skill set. If anything, most current nursing and medical education explicitly frames these tools as extending the bedside exam rather than replacing the judgment behind it, on the reasoning that a clinician who understands what a properly performed history and physical exam is supposed to find is also the one best equipped to know when a number on a screen doesn’t match what they’re seeing in front of them.

Closing

Key takeaways on the cardiovascular assessment

A cardiovascular assessment holds together as a sequence: a focused history sets up what to expect, inspection and palpation gather findings before a stethoscope ever comes out, and auscultation at five standardized sites, in more than one position, completes the picture. Standardized scales, the Levine grading system for murmurs, the current blood pressure categories, a consistent pulse and edema grading convention, are what make an individual clinician’s findings usable by everyone else on the care team, which is as much the point of learning them as any single number is. Some pieces of this exam that were taught for decades, Homans’ sign chief among them, and the precise capillary refill cutoff close behind it, have turned out to rest on weaker evidence than their long presence in textbooks suggests, and current practice has been quietly correcting for that even where teaching materials haven’t fully caught up. Technology is changing what surrounds this exam, point-of-care ultrasound and digital stethoscopes especially, without changing what the exam is fundamentally for: turning a patient’s symptoms and a clinician’s hands and ears into a clear, shareable, and reasonably reproducible picture of how the heart and vessels are actually functioning.
