Ejection fraction

An ejection fraction (EF) related to the heart is the volumetric fraction of blood ejected from a ventricle or atrium with each contraction (or heartbeat). An ejection fraction can also be used in relation to the gallbladder, or to the veins of the leg. Unspecified, it usually refers to the left ventricle of the heart. EF is widely used as a measure of…
