Left Ventricular Ejection Fraction

Preferred Label : Left Ventricular Ejection Fraction;

NCIt related terms : Ejection Fraction; LVEF; EF, %;

NCIt definition : The fraction of the left ventricular end diastolic volume ejected with each beat. The left ventricular ejection fraction is equal to the left ventricular stroke volume divided by the left ventricular end diastolic volume.;

Alternative definition : CDISC: The percent or fraction of the left ventricular end diastolic volume ejected during systole that can be measured by visual estimation or calculation.; ACC/AHA: The fraction of blood expelled from the left ventricle with each cardiac systole (stroke volume/end diastolic volume);
