WebMar 19, 2011 · If the ventricles spent an equal length of time in systole and diastole, the mean arterial pressure could simply be estimated as the mathematical average of systolic and diastolic pressure values. In reality, however, the ventricles spend approximately one-third (1/3) of their time in systole, and two-thirds (2/3) in diastole (see Fig. 1). WebThe period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( Figure 19.3.1 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole.
