Ejection Fraction Calculator

Calculate left ventricular ejection fraction from echocardiogram measurements

Enter Measurements

End-Diastolic Volume (EDV) - mL

Volume at end of filling (normal: 65-240 mL)

End-Systolic Volume (ESV) - mL

Volume at end of contraction (normal: 16-143 mL)

Formula:

EF = (EDV - ESV) / EDV × 100%

EF Categories

≥55%Normal (HFpEF if symptomatic)

45-54%Mildly Reduced (HFmrEF)

35-44%Moderately Reduced

<35%Severely Reduced (HFrEF)

Understanding Ejection Fraction

Ejection Fraction (EF) measures the percentage of blood pumped out of the heart with each contraction. It's a key indicator of heart function, especially for diagnosing and managing heart failure.
