What would be the heart rate of a person if the cardiac output is 5 L , blood volume in the ventricles at the end of diastole is 100 mL and at the end of ventricular systole is 50 mL ?

Question

Accepted Answer

Correct answer: C. (c) Cardiac output = Stroke volume Heart rate Given, Cardiac output =5 L or 5000 ml Blood volume in ventricles at the end of diastole =100 ml Blood volume in ventricles at the end of systole =50 ml Therefore, Stroke volume =100-5.0=50 ml. So, 5000 ml=50 ml Heart rate Heart rate =100 beats per minute
