Q. Which would be the heart rate of a person if the cardiac output is 5L, blood volume in the ventricles at the end of diastole is 100 mL and at the end of ventricular systole is 50 mL?
A) 50 beats per minute
B) 75 beats per minute
C) 100 beats per minute
D) 125 beats per minute
Explanation
[Solution] Stroke volume = 100 - 50 = 50 mL; heart rate = 5000/50 = 100 beats per minute. Answer (3).
