Aim: The aim is to study the unknown role of the arteriovenous anastomoses (AVA). Methods: Methodology used in this study include medical consultations, information search in literature, participation in medical conferences, correspondence with scientists, discussions with Russian leading cardiologists. Results: Many cardiologists agree that the role of small or large AVA in human circulatory system is still poorly understood. We have found that along with the positive role, the anastomoses, especially large AVA, periodically have pathological effects on the cardiovascular system. The device “Cardiocode” is used for testing. Large arteriovenous anastomoses (AVA) can be opened under the influence of stress. Periodically, the pressure changes in the arteries and veins. Vena cava expands and its wall's tone increases and pulse waves start to move through the AVA along the elastic walls of the vena cava to the right atrium. Mechanical impulses can excite heart from various points of the atria or ventricles, disrupting the sinus rhythm. The results include: extrasystoles appearance, tachycardia attacks and at the same time the blood flow blocks on almost all the peripheral segments of circulatory system, edemata appearance. Increased venous pressure stops the capillary circulation, which eventually leads to heart failure, even in a healthy heart. Serious metabolic disorder appears that leads to disease comorbidity and Sudden Cardiac Death (SCD). Conclusions: The absence of breathing exercises, drinking large amounts of beer, smoking, and lack of exercise and presence of large AVA can sometimes lead to a variety of diseases and metabolic diseases. To get rid of the attacks of cardiac arrhythmias and the prevention of SCD, we need to find some way to suppress the mechanical waves running through AVA, as “reentry” phenomenon has a mechanical nature. It is necessary to continue studying the AVA to develop new measures for neutralizing the pathological events associated with the open AVA.
