If the SA node fails to initialize, the AV junction can take over as the main pacemaker of the heart. The AV junction consists of the AV node, the bundle of His, and the surrounding area; it has a regular rate of 40 to 60bpm.

Sa av bundle of his

The bundle of His is located in the interventricular septum. It also comprises pacemaker cells, and they can generate their own action potentials spontaneously at a rate of 40-60 beats per minute. The atrial depolarization spreads to the atrioventricular (AV) node, passes through the bundle of His (not labeled), and then to the Purkinje fibers which make up the left and right bundle branches; subsequently all ventricular muscle becomes activated. After initial sinoatrial nodal excitation, depolarization spreads throughout the atria. The bundle of His is the part of the heart's electrical system that controls the beating of the cardiac muscle. Directly before the bundle of His in the electrophysiological pathway of the heart is the atrioventricular (AV) node. Together, they make up the area of the heart called the AV junction.

2021-02-15 · The AV node contains only myocardial cells, no pacemaker cells. The bundle of His connects the AV node to the left and right bundle branches that control the contraction of the ventricles. The pacemaker cells within in the bundle can send electrical pulses at an accelerated rate of 40 to 60 beats per minute.

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 If the SA node or atria are not functioning properly, the AV node can act as a pacemaker, firing at 40-60 impulses/min. courtesy of ECGpedia.org The Bundle of His (AV bundle) leaves the AV Node and splits into the right and left bundle branches, which innervate the ventricles via Purkinje Fibres . SA node creates an action potential or excitation signal. The wave of excitation spreads across the atria and makes them contract.

It descends down the membranous part of the interventricular septum, before dividing into two main bundles: The AV node tapers down into the bundle of His, which passes into the ventricular septum and divides into two bundle branches, the left and right bundles. Sometimes the 'left and right bundles of His' are called Purkyně or Purkinje fibers . That AV node is pretty smart. So once that AV node allows that electrical impulse to pass through, it moves to the bundle of His, which is located just below that AV node, and from there it separates through the left and right bundle branches.

Figure 2. The conduction system of the heart. Left: Normal excitation originates in the sinoatrial (SA) node then propagates through both atria. The atrial depolarization spreads to the atrioventricular (AV) node, and passes through the bundle of His to the bundle branches/Purkinje fibers.
