Question

Quizplus · Accepted Answer

The double product (DP = heart rate x systolic blood pressure) is a measure of the metabolic load placed on the heart during exercise. It is commonly used to estimate the level of exertion and intensity of exercise, and to monitor cardiovascular response to exercise. Choice A is incorrect because the double product only estimates systolic blood pressure, not diastolic pressure which is also important in blood pressure measurement. Choice B and C are irrelevant as they do not involve the cardiovascular system.
