The atrioventricular bundle is part of the cardiac conduction system that connects the entire right and left atria. It consists of two bundles: - The fibrous atrioventricular bundle (AV fiber), which connects both atria and supplies the bundle of His. - The conduction bundle of His, which originates from the posterior part of the right atrium, passes through the septum between the atrium and the ventricle and ends at the right atrial appendage.
Functions of the atrioventricular bundle: 1. It provides an electrical impulse that causes contraction of both
The atrioventricular bundle (lat. f. atrioventricularis) is one of the important anatomical formations in the human cardiovascular system. It connects the atria and ventricles of the heart and plays an important role in regulating heart rhythm.
The atrioventricular bundle consists of several muscle fibers that form a dense structure called the hissa bundle. This bundle passes through the septum between the atria and ventricles of the heart and ends at the bottom of the ventricles, where it connects with the fibers of the ventricular muscle.
The atrioventricular bundles perform several important functions in the body. First, they provide communication between the atria and ventricles, which allows the heart to pump blood from one part to another. Secondly, they regulate heart rhythm by controlling the rate of contraction of the ventricles. Thirdly, they are involved in the formation of electrical impulses that trigger heart contractions.
In case of damage to the atrioventricular bundle, various heart rhythm disturbances, such as arrhythmias and blockades, may occur. In addition, certain diseases, such as myocardial infarction, can damage the bundle and impair its function.
Studying the anatomy of the atrioventricular bundle is important for understanding the functioning of the cardiovascular system and can be useful in the medical diagnosis and treatment of heart disease.
