WebThe ejection fraction (EF) formula equals the amount of blood pumped out of the ventricle with each contraction (stroke volume or SV) divided by the end-diastolic volume (EDV), the total amount of blood in the ventricle. To express as a percentage, you would multiply by 100. So, EF = (SV/EDV) x 100. In other words, the ejection fraction is the ... WebEjection Fraction (EF) is a percentage of blood pumped by the LV with each contraction. Many factors can affect ejection fraction including preload, afterload, and contractility. A normal EF ranges from 55-69%, and is calculated using the following equation: Ejection fraction (EF) in percentage is defined as: EF (%) = SV/EDV x 100.
