Definition of ejection fraction in English English dictionary
The ratio of the stroke volume (the blood ejected from the left ventricle in one cardiac cycle) to the total volume of the end diastolic volume of the left ventricle
The amount of blood pumped out of a ventricle during each heart beat The ejection fraction evaluates how well the heart is pumping; Normally 50 - 70 percent
The amount of blood that is pumped out of the heart with a single beat compared with the amount that was in the ventricle before the heart contraction
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)
The fraction of the end-diastolic volume that is pushed into the aorta during systole ejection fraction=stroke volume/end-diastolic volume Press the "back" button to return to where you came from
A measurement of blood that is pumped out of a filled ventricle The normal rate is 50 percent or more
This is the amount of blood pumped out of the heart with each beat It is expressed as a percent Normal value is 45-55% It can be measured by special tests
the percent of the left ventricular volume that is ejected in one cardiac contraction; stroke volume divided by ventricular end-diastolic volume
The efficiency with which blood is moved from the ventricles to the body expressed in a percentage
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
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
