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 Cardiac Cycle. The cardiac cycle is divided into four separate periods, two of the periods occurring during the relaxation phase (Diastole) of the cardiac muscle, and two periods occurring during the contraction phase (Systole) of the cardiac muscle. The first phase of the cardiac cycle is the Ventricular Filling Period (VFP) during diastole. At the start of VFP, the heart is in a polarized state and blood is moving through the atria past the heart valves and into the ventricles.
