What is the electrical and mechanical events that take place during R wave?

During the R wave of an electrocardiogram (ECG), there is depolarization of the ventricles, which leads to the contraction of the ventricular muscles. This electrical event is followed by the mechanical event of ventricular systole, where the ventricles forcefully pump blood out to the body and lungs.

What is the sound of second heart sound?

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.
