The first phase of ventricular systole is known as isovolumetric contraction. During this phase, the pressure in the ventricles increases sharply, but is not yet high enough to open the aortic and pulmonary valves. Therefore, no blood leaves the ventricles.
The time at which ventricular contraction occurs is called systole. In a blood pressure reading, the systolic pressure is typically the first number recorded. For example, with a blood pressure of 120/80 (120 over 80), the systolic pressure is 120. By 120 is meant 120 mm Hg (millimeters of mercury).
