@drbahaadmourInside the Heart | Blood Leaves and Remains 🔄🫀 ────────── Your heart does not empty completely with every beat. 🔬 The left ventricular ejection fraction, or LVEF, measures how much blood the left ventricle pumps out during contraction.

A value of 64% is within the usual normal range. Blood then
