The heart has a biological equivalent of an electrical wiring system. A special area of the heart, the sinuatrial node is the first component of the conducting system of the heart. It is the pacemaker for all of the contractile tissue. From it the impulse originates which passes down the conducting system controlling the beat. Vascular damage or simple oxygen lack may cause it to stop.
