WebbSecond Heart Sound Audible expiratory splitting means > 30 msec difference in the timing of the aortic (A 2) and pulmonic (P 2) components of the second heart sound. Splitting of S 2 is best heard over the 2nd left intercostal space The normal P 2 is often softer than A 2 and rarely audible at apex Differential Diagnosis of P 2 audible at apex WebbSplit S1. S1 is generated by closure of the mitral and tricuspid valves. These paired left- and right-sided valves do not close at exactly the same time, but the human ear cannot distinguish sounds that are 0.02-0.03 seconds apart as 2 separate sounds. When conditions further delay tricuspid valve closure, a split S1 can be appreciated.

Webb21 dec. 2024 · Splitting of S1. First heart sound has two components: the mitral and the tricuspid components. 1. The mitral valve closes slightly before the tricuspid valve. This gives rise to splitting of the first heart sound. 2. But this splitting cannot be detected by auscultation, because both the components are very low-pitched and merge into each ...
