ejection fraction

fraction /frac·tion/ (frak´shun)

1. a portion of something larger.

2. in chemistry, one of the separable constituents of a substance.frac´tional

ejection fraction the proportion of the volume of blood in the ventricles at the end of diastole that is ejected during systole; it is the stroke volume divided by the end-diastolic volume, often expressed as a percentage. It is normally 65 ± 8 per cent; lower values indicate ventricular dysfunction.

plasma protein fraction a preparation of serum albumin and globulin obtained by fractionating source blood, plasma, or serum from healthy human donors; used as a blood volume supporter.

ejection fraction

The blood present in the ventricle at the end of diastole and expelled during the contraction of the heart.

Ejection fraction

The fraction of all blood in the ventricle that is ejected at each heartbeat. One of the main advantages of the MUGA scan is its ability to measure ejection fraction, one of the most important measures of the heart's performance.

ejection fraction (EF),

the fraction of the total ventricular filling volume that is ejected during each ventricular contraction. The normal EF of the left ventricle is 65%.

ejection fraction

in echocardiography, the fractional volume of blood leaving the left ventricle in systole.

ejection fraction

Left ventricular ejection fraction Cardiology The percentage of blood present in the left ventricle that is effectively pumped forward during systole to supply the peripheral circulation. See Congestive heart failure.
