A patient has a cardiac output of 7,500 mL/min and a stroke volume of 50 mL. What is his pulse rate?

The pulse rate is the number of times (per minute) the arteries expand and contract in response to the pumping action of the heart. The pulse rate is exactly equal to the heart rate, as the contractions of the heart cause the increases in blood pressure in the arteries that lead to a noticeable pulse.Cardiac output = stroke volume x heart rateHeart rate = cardiac output / stroke volume= 7500/50 = 150 beats/min
