WebA single cycle of cardiac activity can be divided into two phases - systole and diastole. The cardiac cycle is then further divided into three stages - atrial systole, ventricular systole, … WebEach cardiac cycle consists of five repeating phases or stages, which are shown below. The end of one cycle immediately precedes and prepares the heart for the start of the next cycle. Because it is cyclic, selecting a starting point for the cardiac cycle is somewhat arbitrary, and any phase can serve as the starting point.
