Anatomy and Pathology of the Conduction System of the Human Heart

  • Thomas N. James
Part of the Developments in Cardiovascular Medicine book series (DICM, volume 3)


In the normal rhythm of the human heart an electrical impulse originates within the sinus node and courses by way of internodal pathways to the AY (atrioventricular) junction where it enters the AV node and passes to the His bundle for distribution through its right and left bundle branches to the ventricular myocardium. To describe the normal and abnormal anatomy of the responsible structures I will use the same sequence in which electrical activation occurs. When disturbances of either rhythm or conduction occur, the physiological sequence of activation can and often does vary, but the normal arrangement and its understanding is still the fundamental basis for unraveling how these disturbances originate and behave.
