Cardiac output will not rise sufficiently with exercise if the heart rate response with exercise is blunted. Normally you expect the heart rate to increase progressively with increasing intensity of exercise. If it is blunted, it is known as chronotropic incompetence. As the blood vessels in exercising muscles take up more blood needed for the exercising muscles, the flow to the brain will decrease if cardiac output does not increase with exercise. Hence the person is likely to faint during exercise when there is chronotropic incompetence.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cardiac output is the product of stroke volume and heart rate.
