Listen systematically: heart sounds then murmurs. While listening, palpate the
carotid artery: the carotid upstroke corresponds to systole (
Heart sounds The 1st and 2nd sounds are usually clear. Confident pronouncements
about other sounds and soft murmurs may be dicult. Even senior colleagues may disagree with one another, before deferring to an echocardiogram.
The 1st heart sound (S1) represents mitral (M1) and tricuspid (T1) valve closure.
Loud S1 occurs in mitral stenosis. The narrowed valve orifice limits ventricular filling so
there is no gradual decrease in flow towards the end of diastole. The valves are, there­fore, at their maximum excursion at the end of diastole, and so shut rapidly leading to a loud and palpable (the ‘tapping’ apex) S ened, eg if the

chrony in the closure of mitral and tricuspid valves.
The 2nd heart sound (S2) represents aortic (A2) and pulmonary valve (P2) closure.
Soft A2 occ urs in aorti c steno sis.
Loud A2 can occur in tachycardia, hypertension, and transposition, though diagnostic
discrimination is limited in clinical practice.
P2 is loud i n pulm onary hypert ensio n and soft in pulmonary stenosis.
Splitting of S2 is best heard in the pulmonary area:
Normal splitting in inspiration due to the variation of right heart venous return
with respiration, delaying the pulmonary component.
Wide splitting occurs in right bundle branch block, pulmonary stenosis, deep in-
spiration, mitral regurgitation, and ventricular septal defects (

Additional sounds
3rd heart sound (S3) occurs just after S2, due to rapid ventricular filling. This can be due to increased volume load (mitral regurgitation, cardiomyopathy), or physiology (pregnancy). It is low pitched and best heard with the bell. It can be distinguished from the ‘pericardial knock’ of constrictive pericarditis or restrictive cardiomyopathy as this is higher pitched and associated with constrictive changes in the

Think: ‘What do I expect to hear?’ Be guided by symptoms and signs before aus-
cultation (but not dictated to: don’t let your expectations determine auscultation).
Use the stethoscope correctly: remember that the bell is good for low- pitched
sounds (eg mitral stenosis) and should be applied gently. The diaphragm filters out low pitches, making higher- pitched murmurs easier to detect (eg aortic regurgita-

Grading intensity of heart murmurs
The following grading is commonly used for murmurs: systolic murmurs from

to 6 and diastolic murmurs from 1 to 4 (as they cannot reach grading 5 or 6).

Prosthetic valve murmurs
Prosthetic valves Created either from synthetic material (mechanical pros-
thesis, see prosthetic sounds,
p42) or from biological tissue (bioprosthesis). The
choice of prosthesis is determined by the anticipated lifespans of the patient and the graft, and the risks of anticoagulation (including plans for pregnancy). Three mechanical valve designs exist: the caged ball valve, the tilting disc single leaflet valve, and the bileaflet valve. Tissue valves are made from porcine valves or bo­vine pericardium.
Prosthetic aortic valves All produce a degree of outflow obstruction and thus
have an
. The intensity of this murmur increases as the valve fails. Ball and cage valves (eg Starr– Edwards) and tissue valves do close completely in diastole and so a diastolic murmur warrants assessment for valve failure.

Eponymous signs of aortic regurgitation
de Musset’s sign: head nodding in time with the pulse.
Müller’s sign: systolic pulsations of the uvula.
Corrigan’s sign: visible carotid pulsations due to a rapid systolic rise and a rapid
diastolic collapse.
Quincke’s sign: capillary nailbed pulsation in the fingers.
Traube’s sign: ‘pistol shot’ femorals, a booming sound heard over the femorals.
Duroziez’s sign: to- and- fro diastolic murmur heard when compressing the
femorals proximally with the stethoscope.
