Welcome to the

What is the Second Heart Sound?
The second heart sound is created when the aortic valve and pulmonic valve close. The second heart sound occurs at the beginning of diastole. It may have two audible components caused by the separated (in time) closing of the aortic and pulmonic valves. We provide two courses that cover second heart sounds, as described below.
