The complete cycle of events in the heart from the beginning of one heart beat to the beginning of the next; an electrical impulse conducted through the heart muscle that constricts the atria which is followed by constriction of the ventricles is cardiac cycle. 

The amount of blood pumped out by the ventricles in a given period of time is cardiac output

CARDIAC CYCLE =  1 complete systole + 1complete diastole. = 0.8 sec.

CARDIAL OUTPUT = stroke volume + heart rate.

The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, followed by a period of robust contraction and pumping of blood, dubbed systole.
