Question

What would be the cardiac output of a person having 72 heart beats per minute and a stroke volume of 50 ml?

• A. 5000 ml
• B. 3600 ml
• C. 7200 ml
• D. 360 ml

Answer 1

The correct option is B

3600 ml

Cardiac output (Q) is the volume of blood pumped by the heart, in particular by a ventricle, in a minute.

Cardiac output is equal to the stroke volume (SV) multiplied by the heart rate (HR).

So, the cardiac output will be 3600 ml.
