It is controlled by an electrical conduction system special to the heart that allows a impulse begun by the sinoatrial node (SA node) to be propagated throughout the cardiac muscle. The heart contracts after stimulation but in an ordered stimulation that allows efficient contraction of the heart. The atrium contract first and then the ventricles after a short pause.
