bundle of His

H0216700 (hĭs)n. The bundle of cardiac muscle fibers that conducts the electrical impulses that regulate the heartbeat, from the atrioventricular node in the right atrium to the septum between the ventricles and then to the left and right ventricles. Also called atrioventricular bundle.

[After Wilhelm His, Jr. (1863-1934), Swiss physician.]

a′trioventric′ular bun`dle

n. a bundle of conducting muscle fibers in the heart leading from the atrioventricular node to the ventricles. Also called bundle of His.

[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

bundle of His

(hĭs)n. The bundle of cardiac muscle fibers that conducts the electrical impulses that regulate the heartbeat, from the atrioventricular node in the right atrium to the septum between the ventricles and then to the left and right ventricles. Also called atrioventricular bundle.

bundle of His

A bundle of specialised cardiac muscle fibres which carries the electric impulses for the co-ordinated contraction of the heart. The bundle begins at the AV node located at the inferior interatrial septum, and passes into the subendocardium through the right fibrous trigone to the interventricular septum, after which it divides into right and left limbs that pass along either side of the septum, branching to the walls of the ventricles.

bundle of His

The short bundle of specialized heart muscle fibres that conducts electrical impulses from the ATRIOVENTRICULAR NODE to the conducting bundle that splits at the top of the interventricular septum. Also known as the atrioventricular bundle. (Wilhelm His, 1831–1904, German professor of medicine).

bundle of His

atrioventricular bundle

a group of specialized muscle fibres in the mammalian heart carrying electrical signals from the ATRIOVENTRICULAR NODE down the septum between the ventricles and eventually dividing up into Purkinje fibres. See HEART and Fig. 189 .
