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.
Ejection fraction is a measurement of the percentage of blood leaving your heart each time it contracts. When the heart beats, it contracts or squeezes and then relaxes. During heart contraction, it pushes the blood within the pumping chamber out. When your heart relaxes, the chambers or ventricles refill with blood.
