What is the normal left ventricular ejection fraction (LVEF) range?

The normal left ventricular ejection fraction (LVEF) range is typically defined as being between 55% and 70%. This range indicates the percentage of blood that is pumped out of the left ventricle with each heartbeat, reflecting the heart's efficiency in circulating blood throughout the body. An LVEF within this range is associated with a healthy and adequately functioning heart. Values below this range could indicate some degree of cardiac dysfunction or heart failure, while values above 70% may suggest hyperdynamic circulation often seen in certain conditions, which may not be considered normal in a resting individual. Understanding LVEF is crucial in cardiac assessments as it is a key indicator of the heart’s mechanical performance.
