If a person has a hea rate of 70 beats/min, a left ventricular end diastolic volume of 100 ml, and an ejectionfraction of 0.50, then the cardiac output is
Cardiac output = hea rate x stroke volume. The ejection fraction = stroke volume/left ventricular end- diastolic volume (LVEDV). Therefore, stroke volume ejection fraction x L VEDV, or 0.50 x 100 ml = 50 nit Cardiac output = 50 ml x 70 beats/mm = 3500 mI/minute, or 3.5 liters/mm.
