What Is Ejection Fraction (EF)? Manhattan Cardiology
WebCardiac output (CO) Cardiac output is the product of stroke volume (SV) and heart rate (HR). CO = HR · SV. ... Ejection fraction (EF) Ejection fraction is the fraction of the end-diastolic volume (EDV, i.e blood volume in the ventricle at the end of diastole) that is pumped out during systole. Currently, two-dimensional (2D) echocardiography ... Web2) Cardiac output in mL/min / Heart rate in bpm. Example calculation from the ejection fraction calculator: for a normal range stroke volume of 70 mL and a left ventricular EDV value of 120 mL, the ejection fraction is: 70/120 = 0.58, meaning in percentage 58%. Normal EDV for the left ventricle is between 121 mL and 163 mL. WebAn ejection fraction outside of the normal range could mean a variety of things: 40% to 49% is mid-range ejection fraction: The heart’s pumping ability is slightly below normal.
