EF stands for Ejection Fraction.
What does EF mean?
the percentage of blood pumped out of the heart with each beat
EF stands for ejection fraction, a measure of how well the heart pumps. It is the percentage of blood in a filled ventricle that is pumped out with each heartbeat, usually referring to the left ventricle. A normal left ventricular ejection fraction is about 50 to 70 percent. A reduced EF is a key sign of heart failure with reduced ejection fraction, while heart failure can also occur with a preserved EF. It is most often measured by echocardiogram, and is sometimes written LVEF for the left ventricle.
When is EF used?
EF is documented in cardiology and general medical notes and guides the diagnosis and treatment of heart failure.
Frequently asked questions
What does EF stand for?
EF stands for ejection fraction, the percentage of blood pumped out of the heart with each beat.
What is a normal ejection fraction?
A normal left ventricular ejection fraction is about 50 to 70 percent.
What does a low EF mean?
A reduced EF is a key sign of heart failure with reduced ejection fraction, meaning the heart pumps less effectively.
How is EF measured?
It is most often measured by an echocardiogram, and may be written LVEF for the left ventricle.
