Cardiac output may increase by:

Question

Quizplus · Accepted Answer

Cardiac output is the amount of blood pumped by the heart in one minute. It is determined by multiplying the heart rate (number of beats per minute) by the stroke volume (amount of blood pumped with each beat). Therefore, an increase in either heart rate or stroke volume or both can lead to an increase in cardiac output. Option E is the only choice that includes both a greater than normal stroke volume and heart rate, which would result in the greatest increase in cardiac output.
