Frequently asked questions
Ejection fraction: What does this calculator compute?
Calculates left ventricular ejection fraction from EDV and ESV (e.g. biplane Simpson method) or from LVEDD and LVESD via the Teichholz volume estimate, with stroke volume and the limits of the ASE/EACVI recommendation.
