Atrioventricular system

The atrioventricular system (AVS) is one of the most important structures in the cardiovascular system. It consists of two atria and a ventricle, which are located at the top of the heart. The atria receive blood from the lungs and other tissues of the body, and the ventricle pushes the blood into the arteries.

This system works like a pump that pumps blood throughout the body. Blood passes through the atria and ventricle, where it is saturated with oxygen and carbon dioxide. The blood then enters the arteries, which carry it throughout the body.

RFS also plays an important role in regulating blood pressure. When the heart beats, blood passes through the atria and the pressure in them increases. This causes the ventricle to contract and push blood out of the heart and into the arteries. The pressure in the arteries drops, which helps maintain normal blood pressure.

However, if the RV does not work properly, it can lead to various heart diseases such as arrhythmia, heart failure and others. Therefore, it is important to monitor the health of this system and consult a doctor if any symptoms occur.

Introduction

The atrioventricular system (AVS) is also called the atrioventricular system, the heart pump, or the contractile mechanism of the heart. The coordinated actions of this system ensure full cardiac output and ensure consistent functioning of the ventricles and atria. Synchronization of contractions is ensured by the regulation of the passage of the excitation wave through the heart through effective contractility and desiccation of various parts of the heart muscle. The PVC is a complex network of anatomical, electrical and mechanical connections that are united by the process of contraction. The development of disturbances in the system leads to a decrease in pumping function and high rigidity of the myocardial chambers, which is the cause of numerous heart diseases. Currently, PVC is the object of close study not only by cardiac surgeons, but also by cardiologists, geneticists and biophysicists. Separate studies are devoted to studying the participation of this system in the aging processes of the body, various cardiac arrhythmias, myocardial diseases, microvascular pathology and ontogenesis of the heart. We will study in detail the anatomical and physiological structure of the atrioventrilular system, as well as its pathological changes and methods of treating impaired function. Anatomy The cardiocentral properties of the RV system have been studied since the mid-20th century. The term "atrioventricular" (s. attriovenetroicalire) was introduced around 1959 by Eduard L. Lise. The observations of these authors confirmed the fundamental similarity of electrical activity in the atria and ventricles. Atriovenricular connections also represent a coordination function. Research by foreign and domestic scientists has made it possible to identify the main regular features in the structure and functioning of PVCs and to summarize the results of their long-term study. Atriovenoventicular disorder syndrome consists of a complex of symptoms indicating a failure of the coordinated functioning of the atrium and the heart, reducing the efficiency of the heart pump. Violation of the contractile function of the heart is manifested by a decrease in resistance against the background of development, as well as the possibility of a fatal outcome.
