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. It is known as stroke volume. <br /> <br /> Stroke volume (SV) is the volume of blood pumped by the right/left ventricle of the heart in one contraction.
