Structure of ventricular systole in patients with atherosclerotic cardiosclerosis complicated by atrial fibrillation

Atrial fibrillation in the form of permanent and paroxysmal forms often complicates the course of atherosclerotic cardiosclerosis [1, 2, 3, 12, 16, 17]. Atrial fibrillation, despite the absence of parallelism with the degree of structural changes in the heart, is the result of significant shifts in the physiological properties of the heart muscle and, regardless of the causes that caused it, it can lead to severe circulatory insufficiency with retrograde stagnation. However, the constant form of atrial fibrillation and its paroxysms have different effects on intracardiac hemodynamics and the functional state of the myocardium.
