हिन्दीWhat would be the heart rate of a person if the cardiac output is \( 5\text{L} \), blood volume in the ventricles at the end of diastole is \( 100\text{ mL} \) and at the end of ventricular systole is \( 50\text{mL} \)?
Correct answer · Option 1
100 beats per minute
Explanation
Stroke Volume = \( 100 - 50 = 50\text{ mL} \). Heart Rate = Cardiac Output / Stroke Volume = \( 5000\text{ mL} / 50\text{ mL} = 100\text{ beats/min} \).
