@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. For example, an LVEF of 64% means the left ventricle ejects 64% of the blood volume it contains at the end of filling, while about 36% remains inside before the next heartbeat refills it. A value of 64% is within the usual normal range. Blood then
