Ejection fraction is usually expressed as a percentage. A normal heart pumps a little more than half the heartâs blood volume with each beat. (1). A normal LVEF ranges from 55-70%. A LVEF of 65, for example, means that 65% of the total amount of blood in the left ventricle is pumped out with each heartbeat.
The ejection fraction (EF) is an important measurement in determining how well your heart is pumping out blood and in diagnosing and tracking heart failure. A significant proportion of patients with heart failure happen to have a normal ventricular ejection fraction at echocardiography during examination. Previously called diastolic heart failure, it is now referred to as heart failure with normal ejection fraction (HFNEF) or HF with preserved ejection fraction.
