Imaging of the physiology of the mammalian heart is the art that allows meaningful mathematical expression defining EF. Noninvasive cardiac imaging is a worldwide utility enabling study of cardiac performance reproducibly and inexpensively. Simplified, ejection fraction is a mathematical product allowed by cardiac imaging. The original encyclopedi...

Type: Term Definitions: 1. the fraction of the blood contained in the ventricle at the end of diastole that is expelled during its contraction, the stroke volume divided by end-diastolic volume, normally 0.55 (by electrocardiogram) or greater; with the onset of congestive heart failure, the ejection fraction decreases, sometimes to 0.10 or even les...

Ejection fraction: The portion of blood that is pumped out of a filled ventricle as a result of a heartbeat. The heart does not eject all of the blood that is in the ventricle. Only about two-thirds of the blood is normally pumped out with each beat. That fraction is referred to the ejection fraction. The ejection fraction is an indicator of the he...
