What is the difference between heart rate and pulse?
The heart rate is the number of heart beats per unit of time which is usually expressed in beats per minute (bpm). Heart rate is usually measured by sensing devices such as electrodes that pick up the electrical activity of the heart. This electrical activity of the heart regulates contractions of the heart. The pulse rate is commonly measured at any point on the body where an arteries pulsation is transmitted to the surface – often as it is compressed against an underlying structure like bone – by pressuring it with the index and middle finger. The pulse rate is a physical measure of the heart rate.
