There are two phases of the cardiac cycle. These phases are diastole and systole. The dicrotic notch is found during systole, specifically ventricular systole.
Systole is the time when <span>left and right ventricles contract and eject blood into the aorta and pulmonary artery.

Diastole is the time when the ventricles are not contracting or are in a relax mode.
