Assuming a stroke volume output of 75 ml at rest that increases by 24% after exercise, and a heart rate of 65 at rest and 139 following exercise, calculate the cardiac output standing at rest and immediately after exercise. a. 4875/12927b. 4875/10425c. 4875/6045d. impossible; subject would be dead with a heart rate of 139 bpm.

4875/12927.

Explanation:

The cardiac output may be defined as the product of the heart rate and the stroke volume.

Cardiac output= stroke volume ×heart rate

The cardiac output at rest can be calculated as follows:

The stroke volume at rest is 75 and the heart rate is 65.

Cardiac output = 75×65

Cardiac output = 4875 .

The cardiac output after exercise can be calculated as follows:

The stroke volume has been increased by 24%.

Final stroke volume = 75 × 24/100 + 75

Final stroke volume = 93.

Heart rate = 139.

Cardiac output = 139×93

Cardiac output = 12927 .

Thus, the answer is 4875/12927.
