Middle English (Scots) carne, from Scottish Gaelic carn; akin to Old Irish & Welsh carn cairn
Ejection fraction is commonly measured by an echocardiogram and serves as a general measure of a person's cardiac function. Ejection fraction is typically low in patients with the systolic form of congestive heart failure.
An ejection fraction of 60% means that 60% of the total amount of blood in the left ventricle is pushed out with each heartbeat. What's normal? A normal heart's ejection fraction may be between 50% and 70%. You can have a normal ejection fraction reading and still have heart failure (called HFpEF or heart failure with preserved ejection fraction).
