His Bundle


a·tri·o·ven·tric·u·lar bun·dle

[TA] the bundle of modified cardiac muscle fibers that begins at the atrioventricular node as the trunk of the atrioventricular bundle and passes through the right atrioventricular fibrous ring to the membranous part of the interventricular septum where the trunk divides into two branches, the right bundle [TA] (crus dextrum [TA]) of the atrioventricular bundle and the left bundle [TA] (crus sinistrum [TA]) of the atrioventricular bundle; the two crura ramify in the subendocardium of their respective ventricles. Synonym(s): fasciculus atrioventricularis [TA], atrioventricular band, Gaskell bridge, His band, His bundle, bundle of His, Keith bundle, Kent bundle (1) , Kent-His bundle, truncus fascicularis atrioventricularis, trunk of atrioventricular bundle, ventriculonector
The bundle of conduction fibers, first described by Wilhelm His, which originates from the A-V node and descends into the ventricles, before the conduction system splits into bundle branches
