00:00:00 Introduction
Type of S2 splitting
00:00:45 a) Physiological splitting
00:03:25 b) Wide splitting
00:06:50 c) Fixed splitting
00:10:29 d) Paradoxical splitting
00:14:35 Revision
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 on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves. The vibrations of the second heart sound occur at the end of ventricular contraction and identify the onset of ventricular diastole and the end of mechanical systole
