What is the bundle of Kent?

The bundle of Kent is an abnormal extra or accessory conduction pathway between the atria and ventricles that is present in a small percentage (between 0.1 and 0.3%) of the general population.

What happens at the AV bundle?

Next, the signal travels to the AV node, through the bundle of HIS, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract. This signal creates an electrical current that can be seen on a graph called an electrocardiogram, or EKG.

What is the function of the atrioventricular AV Junction?

The atrioventricular node or AV node electrically connects the heart’s atria and ventricles to coordinate beating in the top of the heart; it is part of the electrical conduction system of the heart.

What is the role of the AV bundle in the heart?

This is near the central area of the heart. The bundle of His is also called the atrioventricular bundle. It is a branch of fibers (nerve cells) that extends from your AV node. This fiber bundle receives the electrical signal from the AV node and carries it to the Purkinje fibers.

What is Bachmann’s bundle?

Introduction. Bachmann’s bundle (BB), also known as the interatrial bundle, is well recognized as a muscular bundle comprising of parallel aligned myocardial strands connecting the right and left atrial walls and is considered to be the main pathway of interatrial conduction.

What is Lown Ganong Levine syndrome?

The Lown-Ganong-Levine (LGL) syndrome occurs when an accessory pathway is congenitally present that directly connects the atria to the ventricles, bypassing the AV node similar to the Wolff-Parkinson-White (WPW) syndrome.

What is the difference between the bundle of His and Purkinje fibers?

The bundle of His is a heart muscle that takes part in electrical conduction in the heart. Purkinje fibres are branched fibres that carry the electrical impulse to the ventricles. It is branched into both right and left bundle branches of the heart, and runs through the interventricular septum.

What happens if AV node is damaged?

If your AV node is not working well, you may develop a condition known as heart block. First-degree heart block is when it takes too long for your heartbeat to travel from the top to the bottom of your heart.

What are the 3 functions of the AV node?

It transmits the heart’s electrical signal from the atrium to the ventricle, optimizes the coordination of each heartbeat, and, if atrial fibrillation occurs, protects the ventricles from being bombarded with a dangerous number of electrical signals.

Where is the Bachmann bundle located?

left atrium
In the heart’s conduction system, Bachmann’s bundle (also called the Bachmann bundle or the interatrial tract) is a branch of the anterior internodal tract that resides on the inner wall of the left atrium.

What is the bundle of His and Purkinje Fibres?

Bundle of His is a collection of specialized heart muscle cells that transmit electrical impulses from the AV node in the heart to the muscle cells of the heart wall. Meanwhile, Purkinje fibres are thin filaments that distribute electrical impulses to the ventricle myocardium and activate right and left ventricles.
