WebIn general, second heart sound is produced when the aortic and pulmonic valves are closed. The closure of the aortic valve produces a sound called A2, and the closure of the pulmonic valve produces a sound P2. When these sounds are indistinguishable, a split is heard. This is the second heart sound with a persistent split. Webnumber of beats that can occur in one second is derived.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut.
