The specialized atrioventricular (AV) conducting system is a complex collection of tissues, in which the functional properties vary progressively from the level of the AV node to the termination of the Purkinje fibers in ventricular muscle. A cardiac impulse propagating from atrium to ventricle across a normal AV conducting system must cross the AV node, bundle of His, bundle branches and distal specialized conducting tissues, before depolarizing the ordinary ventricular muscle, unless abnormal bypass tracts are present. Studies of the properties of these various tissues led to a synthesis of information on the nature of normal and abnormal conduction. The discussion in this article is limited to the functional properties of the distal portion of the AV conducting system, which includes the bundle branches, distal subendocardial Purkinje fibers and transitional cells.
