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.
Heart rate and Pulse rate is often same thing. The pulse starts in the heart beat. Every heart beat causes a pulse in the arteries, similar to the ripple a stone makes when itâ¦ is thrown in a pond. The heart rate is the number of times your heart contracts in one minute. The heart is a muscular pump that with each heart beat pumps blood around the body by contraction of the heart's muscle.
