Heart sounds
Other sounds
Murmurs
HEART SOUNDS
 First heart sound (S1): The S1 is associated with
closure of the atrioventricular valves (mitral and
tricuspid) It corresponds to the beginning of
systole.
Abnormally wide splitting: right bundle branch
block, Ebstein’s anomaly
Increased S1: Fever, anemia, excitement,
thyrotoxicosis, short PR interval, mitral
stenosis
Decreased S1: long PR interval and mitral
regurgitation
 Second heart sound (S2): The S2 is associated with
closure of semilunar valves (aortic and
pulmonary). It corresponds to the beginning of
diastole. In every normal child, the s2 is split
during inspiration and single during expiration
(normal splitting of the S2).
HEART SOUNDS
 Widely split S2
Right ventricle volume overload: ASD, partial
anomalous pulmonary venous return)
Right ventricle pressure overload: pulmonary
stenosis
Delay in electrical activation of right ventricle:
right bundle branch block
Early aortic valve closure: mitral regurgitation
 Narrowly split S2
Pulmonary hypertension
Aortic stenosis
Paradoxically split S2
Severe aortic stenosis
Left bundle branch block
HEART SOUNDS
 Single S2
Only one semilunar valve is present: aortic or
pulmonary
atresia,
persistent
truncus
arteriosus
P2 is not audible: transposition of the great
arteries, tetralogy of Fallot, severe pulmonary
stenosis
Aortic closure is delayed: severe aortic
stenosis
P2 occurs early: pulmonary hypertension
 P2 increases in pulmonary hypertension and
decreases in severe pulmonary stenosis,
tetralogy of Fallot and tricuspid stenosis
HEART SOUNDS
 Third heart sound (S3): The S3 is a low-frequency
sound in early diastole and is related to rapid
filling of the ventricle.
It is commonly heard in normal children and
young adults.
A loud S3 is abnormal and is audible in large
shunt VSD, congestive heart failure.
 Fourth heart sound (S4): The S4 is a lowfrequency of late diastole and is rare in infants
and children.
It is always pathologic.
It is seen in conditions with decreased
ventricular compliance.
OTHER SOUNDS
 Ejection clic: It follows the S1 very closely,
therefore it sounds like a splitting of the S1
Valvular aortic and pulmonary stenosis, dilated
great arteries
 Midsystolic click with or without late systolic
murmur
Mitral or tricuspid valve prolapse
 Opening snup: It occurs earlier than the S3 during
diastole
Mitral or tricuspid stenosis
 Pericardial friction rub (frotman)
 Pericarditis
 Pericardial knock
Constrictive pericarditis
