Ejection Fraction Calculator

Calculate stroke volume and ejection fraction from end-diastolic and end-systolic volumes.

 

 

Stroke volume
EF (%)

About this calculator

Use this calculator for SV = EDV − ESV and EF = 100 × SV / EDV. Volumes come from the method you trust (Simpson, 3D). EDV must exceed ESV. This is not a strain report.

Volumes can be entered in millilitres (ml) or fluid ounces (fl oz). Stroke volume follows that choice.

EDV: End-diastolic volume, in ml or fl oz.

ESV: End-systolic volume, in ml or fl oz.

Stroke volume: EDV minus ESV.

EF: Ejection fraction, percent.
