| ejection fraction |
The ejection fraction (EF) or, more correctly, left-ventricular ejection fraction (often abbreviated LVEF) is a measure of how much blood the left ventricle of the heart pumps out with each contraction. The normal left ventricle has an average volume of 100ml and with each heart beat ejects approximately 70 ml, the stroke volume. ...

| ejection fraction |
The ejection fraction is the amount of blood released from the heart's left ventricle when it contracts. It's called a "fraction" because it's expressed as a percentage of the total amount of blood in the left ventricle. For example, an ejection fraction of 80% means that when the left ventricle contracts, 80% of the blood is ejected into the vascular system.
