Atrioventricular bundle

Introduction

The atrioventricular bundle (AVB) is an important part of the heart that provides communication between the left and right atria, as well as between the left ventricle and the RVV. This bundle has several functions, such as conducting the heart impulse and regulating pressure in the heart. In this article we will look at the properties and functions of the PZHV, as well as some possible problems associated with its operation.

Functions of ALHIV

The main function of the RVV is that it conducts the electrical impulses of the heart from one atrium to the other. It also controls pressure in the heart by increasing or decreasing the volume of blood that flows from the left atrium to the left ventricle. This is called regulation of heart rate and blood pressure. Also, the PVH contains fibers from sensory neurons that provide sensitivity to cardiac activity and make it possible to assess the main parameters of cardiac activity (for example, heart rate). Fibers that transmit information about cardiac activity not only from the atria, but also from the aorta, can interact with a nearby structure - the sinoatrial node (SAN), located in the wall of the right atrium. The self-propelled gun produces an impulse that ensures the rhythmic functioning of the heart. The interaction between these structures is supported mainly by groups of nuclei specialized for this, located in both sections of the conduction system of the heart.

The bundles deserve special attention from the point of view of the development of degenerative changes in the myocardium in conditions of damage to the connective tissue structures of the myocardium, for example, in chronic myocardial ischemia, cardiac remodeling in conditions of hypertension or hypertension in patients with prosthetic heart valves.
