Normally, P2 is soft and only heard at the pulmonic region (left parasternal, intercostal space 2), however even in this region A2 is louder. What causes the split second heart sounds? There are believed to be multiple causes for the physiologic splitting of S2.

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split …
