Ventricular Systole

Systole period of contraction of the ventricles of the heart that occurs between the first and second heart sounds of the cardiac cycle the sequence of events in a single. Ventricular systole begins at the apex of the heart which is first to be stimulated and progresses upwardpushing the blood upward toward the semilunar valves.
