Your calculated Ejection Fraction (EF) is: %

Quickly determine your heart's ejection fraction (EF) with our easy-to-use online calculator. Simply input your end-diastolic volume (EDV) and end-systolic volume (ESV) to understand your heart's pumping efficiency. This vital metric helps assess cardiovascular health and can be crucial for monitoring heart conditions.

Formula:

The Ejection Fraction (EF) is a crucial measure of your heart's pumping efficiency. It represents the percentage of blood pumped out of the left ventricle with each contraction.

The formula used is:

Ejection Fraction (EF) = ((End-Diastolic Volume - End-Systolic Volume) / End-Diastolic Volume) × 100%

Where:

  • End-Diastolic Volume (EDV): The total volume of blood in the ventricles at the end of diastole (filling phase).
  • End-Systolic Volume (ESV): The volume of blood remaining in the ventricles at the end of systole (contraction phase).
