If heart rate decreases 30% and stroke volume decreases 10%, then what effect do these decreases have on the cardiac output?

Question

Quizplus · Accepted Answer

Cardiac output is calculated as the product of heart rate and stroke volume. If heart rate decreases by 30% (to 70% of its original value) and stroke volume decreases by 10% (to 90% of its original value), the new cardiac output would be 70% of the original heart rate multiplied by 90% of the original stroke volume, which equals 63% of the original cardiac output. This means the cardiac output decreases by 37% (100% - 63% = 37%).
