Question

How will the cardiac output change if you double the heart rate but reduce the stroke volume by one-half? how will the cardiac output change if you double the heart rate but reduce the stroke volume by one-half? it will not change. it will decrease. it will increase. the answer cannot be determined by the information given?

Answer 1

The answer is that there will be no change.

 The cardiac output is the volume of blood pumped by the heart per unit time.

Multiplying the stroke volume and the heart rate gives you the cardiac output. The cardiac output for a person at rest is approximately 5L per minute.
