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.
As not all of the blood is ejected from the heart with the contraction of the ventricles, the âejection fraction is the amount that is ejected after the ventricle is filled. The main ventricle of the heart valve is the left ventricle, the ejection fraction of the heart is measured here. Therefore, it can be stated that the normal range for the left ventricle (LV) ejection fraction is 55 to 70 percent. slide 2 of 4.
