Detailed explanation-1: -Pulse is the surges of pressure (expansion and then recoil) in an artery that occur when the ventricles contract. Normally, the pulse rate equals the heart rate and averages 70-76 beats per minute while at rest. The pulse most often used is the radial pulse.
Detailed explanation-2: -Systole is the contraction phase of the cardiac cycle, and diastole is the relaxation phase.
Detailed explanation-3: -The pressure of blood inside the arteries during ventricular contraction is called systolic pressure and the pressure in the arteries during ventricular relaxation is called diastolic pressure.
Detailed explanation-4: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase).
