Taking a Pulse (Heart Rate) Your pulse is the rate at which your heart beats. As your heart pumps blood through your body, you can feel a pulsing in some of the blood vessels close to the skin's surface. The usual resting pulse for an adult is 60 to 100 beats per minute. Certain illnesses can cause your pulse to change, so it is helpful to know what your resting pulse is when you are well.
An average heart beats about 100,000 times daily. A pulse rate is measured in the amount of beats in one minute. At rest, a pulse averages 70 to 80 beats per minute. Endurance athletes can have a resting pulse as low as 40 beats per minute.
