"In a healthy heart, specialized cells in the sinoatrial node are responsible for the generation of contractile stimuli that are directed throughout the heart. A direct neural-like pathway propagates this electrical signal from the SA node through the atrial tissue to a central nodal point in the center of the heart, the atrioventricular node. From here, the signal travels down a signal conducting channel (the bundle of His) where it will diverge into a left and right branch that will control the left and right ventricle, respectively.[citation needed]
