- The AV bundle is a strand of conductive tissue that runs through the interatrial septum and into the interventricular septum. The AV bundle splits into left and right branches in the interventricular septum and continues running through the septum until they reach the apex of the heart.

Apr 24, 2023 · 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.

May 10, 2020 · The bundle of His is a collection of heart muscles cells specialised for electrical conduction. These cells receive input from the AVN . 1,4,5 The bundle of His branches into the left and right bundle branches which travel down the interventricular septum .
Aug 17, 2023 · The interatrial conduction pathway, also called Bachmann’s bundle, refers to a preferential pathway of specialized cardiomyocytes that facilitate the conduction of impulses between the atria. The pathway branches from the anterior internodal pathway at the level of the superior vena cava.
5 days ago · About 1% of the cardiac muscle cells in the heart are responsible for forming the conduction system that sets the pace for the rest of the cardiac muscle cells. The conduction system starts with the pacemaker of the heart---a small bundle of cells known as the sinoatrial (SA) node.
Jul 18, 2019 · The atrioventricular bundle, also called the bundle of His, is a bundle of cardiac muscle fibers located within the septum of the heart. This fiber bundle extends from the AV node and travels down the septum, which divides the left and right ventricles.

Aug 1, 2024 · Updated on August 01, 2024. The structure of the heart helps supply blood and oxygen to all parts of the body. It is divided by a partition (or septum) into two halves. The halves are, in turn, divided into four chambers. The heart is situated within the chest cavity and surrounded by a fluid-filled sac called the pericardium.
The bundle of His is a part of the electrical system of the heart. It is a collection of cells that carry electrical signals from the AV node to the bundle branches. The electrical system that controls the heartbeat is made up of several parts that signal the heart muscle to contract.
