A measure of myocardial contractility reflecting the effectiveness of ventricular ejection. It is calculated by dividing the stroke volume by the end diastolic volume, and it is reported as a percentage. A normal ejection fraction is greater than 55 percent.

The amount of blood leaving the heart with each contraction. The amount ejected is measured as a fraction of the total amount of blood in the heart at the beginning of contraction. Normal is 55-75%.

Percentage of blood contained in the ventricle that is ejected during systole (ventricular contraction)

The percentage of blood in the ventricle that is actually pumped into the circulation with each contraction (normal is 60% to 70%); often used as an indicator of left ventricular function.

a measurement of how much blood is pumped by the ventricles with each heartbeat

a measure of ventricular contractility

a way to quantify how well or efficient the heart is beating and to determine the severity of CHF

The amount of blood coming out of the heart with each beat. It takes into account all of the blood in your left ventricle and figures out what percentage is pumped out with each beat. The normal ejection fraction is typically 50% or more.

A measure of how efficient the heart is able to eject blood from the ventricles to the rest of the body. Ejection fraction is expressed in percentages.

The ejection fraction (EF) is a measure of the proportion (or fraction) of blood that is expelled by the ventricle with each contraction, or heart beat. The healthy heart pumps out 55 percent or more of the blood in the left ventricle with each beat. If the ejection fraction falls below 55 percent, it is an indication that the heart muscle is weakened.

is a measurement of the percentage of blood pumped from the heart during each beat. Most commonly the measurement is obtained during an Echocardiogram. Ejection Fraction is a key indicator of heart health and is frequently used by physicians to determine treatment plans for people with heart disease.

The percentage of blood pumped out of the ventricles (lower chambers of the heart) with each contraction. The ejection fraction tells the health care team how well the heart is pumping. A normal EF is 60-70% or greater.

The blood present in the ventricle at the end of diastole and expelled during the contraction of the heart.

the percentage of blood pumped to the body by the left ventricle during every heartbeat. People with a normal, healthy heart typically have an ejection fraction of 55 percent or greater. An ejection fraction of 40 percent or less indicates a weakened heart.

The percentage of blood pumped from the ventricles per heartbeat, used to evaluate the efficiency of left ventricular emptying. Normal EF is 55-65%.

EF is the percentage of blood volume held within the left ventricle at the end of diastole (the End-diastolic Volume, EDV) which is ejected into the vasculature as the Stroke Volume, SV. EF = 100 (SV/EDV)

The percent of blood emptied from the ventricle by the end of a contraction of the heart.

simple test that measures the fraction of blood pumped or ejected from the heart with each beat. Can be measured with an echocardiogram.

The amount of blood released during each contraction of the lower ventricle of the heart. It is usually expressed as a percentage: an ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is expelled with each heartbeat.

The percentage of the total volume of blood that is pumped out of the left ventricle during contraction of the heart.

A measurement of how much blood the heart is pumping with each contraction. People with healthy hearts usually have an ejection fraction of 50% or greater. Ejection fraction can be measured by an echocardiogram or with other diagnostic tests.

percentage of blood that is ejected out of the left ventricle into the aorta with each heart beat

the measurement of the blood pumped out of the heart.

(EF) or, more correctly, left-ventricular ejection fraction, is a measure of how much blood the left ventricle of the heart pumps out with each contraction. The EF is a very important measure in cardiology as it indicates the degree to which the pumping function of the heart is damaged. Patients with CHF, for example, have a low EF.

A measurement of how much blood (what fraction or percentage of blood) the pumping chambers of the heart (the left and right ventricles), are able to pump out or eject and supply to the organs (brain, kidneys, liver, etc.) and muscles of your body. Read more about ejection fraction on the Diagnosis page.

a measurement of blood pumped out of a filled ventricle. The normal rate is 50 percent or more.

refers to the amount of blood ejected out of the left ventricle during systole compared with the total ventricular filling volume. A normal ejection fraction is 65%.

The efficiency with which blood is moved from the ventricles to the body expressed in a percentage.

This is the amount of blood pumped out of the heart with each beat. It is expressed as a percent. Normal value is 50-75%. It can be measured by special tests.

(from Kidsdefib Educational slide show, referring to Tang, et al) A measurement of cardiac function, the percentage of blood in the heart pumped with each beat.

is how much blood is pumped out of the left ventricle (the heart's main pumping chamber) during each heartbeat. It evaluates how well the heart is functioning as a pump.

The amount of blood that is pumped out of a filled ventricle divided by the amount of blood that was in the ventricle at the beginning of the contraction (normal is 50% or more).

Proportion of blood ejected from ventricle with each beat - at rest approximately 70%. A significant amount of blood remains in the chamber.

The percent of the left ventricular volume that is ejected in one contraction of the ventricule. It is calculated as stroke volume divided by ventricular end-diastolic volume.

In cardiovascular physiology, ejection fraction (Ef) is the fraction of blood pumped out of a ventricle with each heart beat. The term ejection fraction applies to both the right and left ventricles; one can speak equally of the left ventricular ejection fraction (LVEF) and the right ventricular ejection fraction (RVEF). Without a qualifier, the term ejection fraction refers specifically to that of the left ventricle.
