Cardiac diastole is the period of time when the heart relaxes after contraction in preparation for refilling with circulating blood. ... Together they are known as complete cardiacdiastole. During ventricular diastole, the pressure in the (left and right) ventricles drops from the peak that it reaches in systole.
