Series of events that constitute a complete heartbeat. Pressure in heart changes. 70% of blood enters ventricles prior to atrial contraction. 30% of the returning blood is pushed in the ventricles.
The heart does not pump all the blood out of the  ventricle. Normally, only about two-thirds of the blood in the  ventricle is put out with each beat. What blood is actually pumped  from the left ventricle is the stroke volume and it, together with  the heart rate, determines the cardiac output.
