01Principles and purposeThe professional or clinical skill and the decisions it supports.
Cardiovascular examination samples circulation at several levels: global perfusion, arterial pulse, venous pressure, cardiac impulse, valve sounds, pulmonary consequences and peripheral fluid state. Treat it as a connected physiological assessment. At first contact, observe colour, temperature, interaction, breathing and monitoring. Ask about current pain, dizziness or breathlessness before positioning. A person with orthopnoea may not tolerate lying flat; examine semi-recumbent and record the limitation. Explain chest exposure and touch, seek permission as the sequence progresses, and offer a chaperone where appropriate. The patient's comfort and right to stop continue after initial consent.
Technique determines whether a finding is interpretable. Count rate and assess regularity before naming a pulse character. Measure blood pressure with a suitable cuff where it changes the assessment. Estimate jugular venous pressure with the torso positioned and the internal jugular pulsation correctly identified; a number without position and landmarks is weak evidence. Inspect and palpate the precordium before auscultation. Identify the first and second heart sounds, then characterise any additional sound or murmur by timing, location, radiation and conditions. Use positional or respiratory manoeuvres only after a baseline examination and explain the movement requested.
Interpret clusters through physiology. An irregularly irregular pulse is compatible with atrial fibrillation but should be confirmed electrically. A displaced apex, third heart sound, basal crackles and oedema can support a congestive pattern, although each feature has alternatives. A slow-rising pulse and an ejection systolic murmur radiating toward the carotids may suggest aortic stenosis, yet symptom history and echocardiography determine consequence and severity. Right-sided venous findings need differentiation from external jugular veins, carotid pulsation and effects of intrathoracic pressure. Always state whether a conclusion is observed, inferred or awaiting confirmation.
Explanation should be proportionate and comprehensible. Begin with what was found, translate the likely meaning, state what remains uncertain and describe the purpose of the next test. Avoid announcing a valve diagnosis as settled on auscultation alone. Check what the patient understood and what concerns the finding raises. In a clinical assessment, a strong presentation links positives and relevant negatives to a short differential and plan. Feedback is most useful when it addresses observable behaviours—landmarking, timing, patient positioning, sign characterisation, synthesis and explanation—rather than an invented score.
Key points
- Start with identity, purpose, consent, pain and positioning; preserve dignity, explain necessary chest exposure and use a chaperone according to the person's wishes and the examination context.
- Survey perfusion and distress before the routine: chest pain, syncope, severe breathlessness, shock features or a new dangerous rhythm require immediate reassessment and escalation.
- Use a coherent sequence through hands, pulse, blood pressure, face, neck, precordium, lungs and peripheral oedema, changing the order when patient safety or mobility demands it.
- Describe rate, rhythm, pulse character, venous waveform, impulse, heart sounds and murmurs separately before combining them into a haemodynamic or structural pattern.
- A murmur is characterised by timing, site, radiation, intensity and manoeuvre response; none of these alone proves severity, and an absent murmur does not always exclude important valve disease.
- Close by stating stability, principal findings, leading explanation, important alternatives, required tests and how the result will be communicated to the patient.
02Situations and prioritiesThe context, relevant information and actions that matter most.
Cool peripheries, altered mentation, hypotension, weak pulse, ongoing ischaemic chest pain or severe pulmonary congestion should interrupt an elective sequence and trigger urgent structured assessment.
Rate, regularity, volume, character and symmetry provide different information; confirmation with an electrocardiogram or vascular assessment is needed before attaching a causal label.
Elevated jugular venous pressure may support raised right atrial pressure, but posture, waveform identification, respiration and local anatomy strongly affect reliability.
Murmur timing and radiation can focus the differential, whereas intensity varies with flow, chest transmission and cardiac output and is an unreliable standalone severity measure.
Raised venous pressure, lung crackles, dependent oedema and displaced impulse become more informative when concordant with symptoms, weight change and physiological observations.
Pulse inequality, delayed capillary refill, scars, oedema and skin temperature may redirect assessment, but chronic vascular change must be separated from an acute circulation problem.
03Assessment and interpretationHow to gather information, assess the situation and recognise uncertainty.
Consider the information, its meaning and its limitations before deciding what follows.
- 01
Complete physiological observations - Why
- Determine current haemodynamic and respiratory risk before detailed interpretation.
- Interpretation and limitations
- Record pulse, blood pressure, respiratory rate, oxygen saturation, temperature and consciousness with timing; a single normal value does not neutralise concerning symptoms.
- 02
Twelve-lead electrocardiogram - Why
- Confirm rhythm and identify electrical evidence relevant to symptoms or examination.
- Interpretation and limitations
- Relate tracing quality and timing to the presentation; an examination impression of rhythm is provisional, and a normal tracing may not exclude intermittent disturbance.
- 03
Focused cardiovascular sign recheck - Why
- Test whether an unexpected finding is reproducible with correct technique.
- Interpretation and limitations
- Repeat pulse assessment, venous landmarking or auscultation under improved conditions and seek senior corroboration when the finding would materially change management.
- 04
Echocardiography when clinically indicated - Why
- Assess cardiac structure, valve function and ventricular performance behind a suspected pattern.
- Interpretation and limitations
- The examination guides the question, while imaging supplies measurements; neither a soft nor loud murmur alone determines the requirement or urgency.
- 05
Relevant blood testing - Why
- Evaluate consequences, contributors and alternative explanations selected from the case.
- Interpretation and limitations
- Choose tests for a defined question such as anaemia, renal function or myocardial injury; indiscriminate panels can create distraction without resolving the examination pattern.
- 06
Patient explanation and teach-back - Why
- Verify that the finding, uncertainty and plan were understood.
- Interpretation and limitations
- Ask the person to describe the next step and warning symptoms in their own words; assent or silence cannot be assumed to mean comprehension.
04Worked approachesCases with ordered reasoning, an action and a check of the outcome.
01Worked caseSystolic murmur with exertional symptomsA fictional case supplies exertional chest tightness and presyncope, a slow-rising pulse, a systolic murmur loudest at the right upper sternal edge with neck radiation, and stable resting observations.+
- 1Confirm consent and present stability, then repeat pulse and murmur characterisation under suitable positioning while asking whether any manoeuvre causes symptoms.
- 2Combine the supplied exertional symptoms, pulse character and ejection murmur into a suspected left ventricular outflow or aortic valve pattern; treat aortic stenosis as the leading hypothesis, not a bedside certainty.
- 3Retain alternatives such as another outflow murmur, transmitted sound or coexisting coronary disease, and identify which history, electrocardiography and echocardiography would refine consequence and structure.
- 4Explain that the examination suggests narrowing affecting blood flow from the heart, that a scan is needed to measure it, and that exertional presyncope raises the priority of clinical review.
- 5Verify the final synthesis contains no invented signs, arrange an appropriate escalation pathway for symptomatic suspected valve disease, and seek feedback on murmur timing, radiation and patient explanation.
02Examination sequenceJoin peripheral and precordial evidenceThe patient is stable, can tolerate a semi-recumbent position and agrees to a cardiovascular examination.+
- 1Inspect general state and hands, assess pulses and blood pressure, then examine the face and neck with explicit attention to perfusion and venous technique.
- 2Inspect and palpate the precordium before listening methodically at valve areas, adding positions or respiration only to clarify a heard sound.
- 3Assess lungs, sacrum or ankles for consequences where relevant, adapting exposure and movement to the patient's comfort.
- 4Re-cover, summarise the circulation pattern and state appropriate completion steps such as observations, electrocardiography or imaging with a reason.
03Explanation structureDiscuss an uncertain new murmurA patient asks whether a newly heard murmur means their heart is failing.+
- 1Acknowledge the concern and ask what the patient understands by the word murmur before supplying more information.
- 2Describe it as a sound heard as blood moves through the heart, explain that several causes range in significance, and avoid equating sound intensity with danger.
- 3State which features and symptoms influence concern and why a scan or review may be proposed.
- 4Check understanding, invite questions, agree how results will be communicated and give symptom-based advice for seeking earlier help.
05Feedback, follow-up and evidenceReview outcomes, seek feedback and identify what to improve.
- Review whether pulse, jugular venous pressure and auscultatory findings can be reproduced by a supervisor under the same patient position and conditions.
- Link every completion test to a specific uncertainty, then check later whether its result supported, revised or refuted the original bedside synthesis.
- Use feedback to refine technical landmarks, timing against the carotid pulse, economical repositioning and avoidance of repeated uncomfortable manoeuvres.
- Record symptoms, observations, examination limitations, escalation decisions, planned investigations and ownership of result communication.
- During longitudinal care, compare functional change and physiology rather than treating an old murmur label as a permanent description of current risk.
06Special situationsVariants, exceptions and circumstances that change the usual approach.
Murmur intensity is contextual
Flow, ventricular function and sound transmission affect loudness; critical disease may not produce the loudest sound, so symptoms and formal assessment remain central.
Position changes the evidence
Venous pressure, oedema and some sounds depend on posture. Report the examination position so another clinician can interpret and reproduce the observation.
Rhythm requires confirmation
Palpation can identify irregularity but cannot fully classify an arrhythmia; electrical recording connects the bedside clue to a defensible diagnosis.
Explanation exposes reasoning
If a finding cannot be described to a patient without leaping to an unsupported diagnosis, the clinical synthesis probably needs clearer separation of observation and inference.
A normal examination has limits
Intermittent arrhythmia, early structural disease and exertional pathology may be absent at rest, so history still determines whether further assessment is needed.
07Common pitfallsFrequent interpretation and management errors.
- 01
Making a patient with orthopnoea lie flat to satisfy a routine rather than adapting position and documenting the limitation.
- 02
Reporting an elevated jugular venous pressure without identifying the pulsation, reference point and torso position.
- 03
Naming a valve lesion after hearing an undifferentiated systolic sound instead of characterising timing, site and radiation.
- 04
Reassuring from a quiet murmur despite exertional syncope, chest pain or breathlessness that changes clinical urgency.
- 05
Explaining investigations without checking the patient's concern, understanding or how and when results will be conveyed.
