This structure controls the heart rate and is called the heart's natural pacemaker. The sinus node signals the heart to speed up during exercise or in situations that are stressful, frightening or exciting. For example, a 10- to 15-minute brisk walk typically elevates the heart rate to 110 to 120 beats per minute. Also, the sinus node increases the heart rate when the body is stressed because of illness. In all of these circumstances, the heart rate increase is a normal response. Likewise, the sinus node signals the heart to slow down during rest or relaxation.
The pulse is the number of heartbeats per minute. The pulse is what you feel over an artery as the pressure inside increases following each heart beat. The average pulse rate is between 60-80 beats per minute. Each time the heart beats, blood is pumped into the arteries.As the blood surges into the arteries during a heart beat, each artery stretches and bulges. This brief bulge of the artery is called a pulse.he average pulse rate is between 60-80 beats per minute. Each time the heart beats, blood is pumped into the arteries.
