Ejection fraction refers to the percentage of that blood your heart pumps out with each beat. “Assuming a normal heart size and rate, when ejection fraction is normal, the heart is pumping a normal amount of blood,” Dr. Finet explains. “We can assume the blood is moving at a normal speed around the body.”

A normal ejection fraction is more than 55%. This means that 55% of the total blood in the left ventricle is pumped out with each heartbeat. Heart failure with preserved ejection fraction (HFpEF) happens when the left ventricle is not filling with blood as well as normal. The ventricle can pump well.

Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function. LVEF is the fraction of chamber volume ejected in systole (stroke volume) in relation to the volume of the blood in the ventricle at the end of diastole (end-diastolic volume). “Normal ejection fraction is between 55-70%,” says Waqar Khan, MD, who’s been providing state-of-the-art cardiology services to the Houston area for over 20 years, and is author of “Be Heart Smart: Understand, Treat, and Prevent Coronary Heart Disease.” For an ejection fraction in the range of 50% to 55%, most of the commonly used tests, if carefully performed, are accurate within a few percentage points (e.g. 55% plus or minus 3%). With respect to the lower limit of “normal” LVEF, it is important to remember that even at rest, the LV pumps a slightly different amount of blood in every beat. A normal ejection fraction is more than 55%.

In patients with normal systolic function, conventional right ventricular apical pacing resulted in adverse left ventricular remodeling and in a reduction in the left ventricular ejection fraction

A normal LVEF reading for adults over 20 years of age is 53 to 73 percent. An LVEF of below 53 percent for women and 52 percent for men is considered low. An RVEF of less than 45 percent is

When the gallbladderempties poorly, the diagnosis of biliarydyskinesia, defined as a gallbladder ejection fractionless than 35%, is made, and cholecystectomy can be considered. There is a subset of symptomatic patients, however, who have an abnormallyhigh ejection fraction, defined as greater than 65%.

Physiology Normal values. In a healthy 70-kilogram (150 lb) man, the stroke volume is approximately 70 mL, and the left ventricular end-diastolic volume (EDV) is approximately 120 mL, giving an estimated ejection fraction of 70 ⁄ 120, or 0.58 (58%). Left ventricular ejection fraction (LVEF) is the central measure of left ventricular systolic function.

Normal EF is 55% to 75%. An EF above 75% may indicate a heart condition, such as hypertrophic cardiomyopathy. An EF between 40% and 55% may indicate

What’s normal? A normal heart’s ejection fraction may be between 50 and 70 percent. You can have a normal ejection fraction measurement and still have heart failure (called HFpEF or heart failure with If the heart muscle has become so thick and stiff that the ventricle holds a smaller than usual A normal ejection fraction is about 50% to 75%, according to the American Heart Association. A borderline ejection fraction can range between 41% and 50%. Even if you have a normal ejection fraction, your overall heart function may not be normal.
