The AV node is continuous with the bundle of His, which gives off a left bundle branch at the top of the interventricular septum and continues as the right bundle branch. The left bundle branch divides into an anterior fascicle and a posterior fascicle.

Bundle of His/Atrioventricular Bundle. The atrioventricular bundle also known as the bundle of His is a continuation of the specialized tissue of the AV node. The bundle of His is a structure that connects with the distal part of the compact AV node, perforates the central fibrous body, and continues through the annulus fibrosus.

The atrioventricular node (AV node) is stimulated. The relatively slower conduction through this node allows time for the atria to contract and complete the filling of the ventricles. 4. The excitation wave travels rapidly through the bundle of His and then throughout the ventricular walls by means of the bundle branches and Purkinje fibers.

A) SA Node, Atria, AV Node, Purkinje Fibers, Bundle Of His, Ventricles. If the pacemaker is in the bundle branches (i.e., ventricles) or purkinje fibers, what is the inherent rate? 20-40 b/min If the SA node‘s discharge is too slow, it is referred to as what? A latent pacemaker When the other foci (AV node, bundle of his, bundle branches, purkinje fibers) become the pacemaker, this is referred to as: Escape Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract.Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum.After a delay, the electrical signal diverges and is conducted through the left and right bundle of His to the respective Purkinje fibers for each side of the heart, as well as to the Since the right atrium is closer to the SA node, it depolarizes first, resulting in pumping action by the right atrium before the left atrium. At the AV node, the impulse is delayed to allow for the ventricles to fill up with blood.

bundle of His: (also, atrioventricular bundle) group of specialized myocardial conductile cells that transmit the impulse from the AV node through the interventricular septum; form the left and right atrioventricular bundle branches Atrioventricular Bundle [Bundle of His] It is a continuation of the AV node and transmits the electrical impulse from the AV node to the Purkinje fibers of the ventricles. Bundle of His begins from the AV node and continues through the annulus fibrosus of the ventricle and penetrates the membranous septum. Proximal cells of the penetrating portion resemble AV node whereas distal cells are similar to cells in the proximal bundle branches.

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

The excitation wave travels rapidly through the bundle of His and then throughout the ventricular walls by means of the bundle branches and Purkinje fibers. Atrioventricular Bundle (Bundle of His), Bundle Branches, and Purkinje Fibers Arising from the AV node, the atrioventricular bundle , or bundle of His , proceeds through the interventricular septum before dividing into two atrioventricular bundle branches , commonly called the left and right bundle branches. The impulses then enter the base of the ventricle at the Bundle of His and then follow the left and right bundle branches along the interventricular septum. These specialized fibers conduct the impulses at a very rapid velocity (about 2 m/sec).

Atrioventricular Bundle. The atrioventricular bundle (bundle of His) is a continuation of the specialised tissue of the AV node, and serves to transmit the electrical impulse from the AV node to the Purkinje fibres of the ventricles. It descends down the membranous part of the interventricular septum, before dividing into two main bundles:
