Ejection Fraction Calculator
A simple and effective tool to calculate Left or Right Ventricular Ejection Fraction (EF) based on stroke volume and end-diastolic volume. This calculator helps assess heart function by determining the percentage of blood ejected from the ventricles during each heartbeat. It’s particularly useful for cardiologists, healthcare providers, and patients monitoring cardiac performance.
Ejection Fraction
Ejection Fraction Calculation Formula
Where
- $$SV$$ = Stroke Volume (mL)
- $$EDV$$ = End-Diastolic Volume (mL)
- $$EF$$ = Ejection Fraction in percentage
This formula calculates the proportion of blood ejected from the ventricle relative to the volume of blood before contraction.
Ejection Fraction is a vital parameter in cardiology used to evaluate how well the heart is pumping blood. An EF value between 50–70% is generally considered normal. A low EF might indicate heart failure or cardiomyopathy, while a high EF could suggest hypertrophic cardiomyopathy. By using stroke volume and end-diastolic volume, clinicians can quickly assess the pumping efficiency of the heart’s left or right ventricle.
