The SA node has the inherent power of generating a wave of contraction and controlling the heartbeat. Thus, it is known as the pacemaker. As the SA node initiates a wave of contraction and controls the heartbeat, the contraction's impulse originates in the heart itself; the human heart is termed myogenic.
