An acute problem of modern cardiology is various violations of the heart rhythm and conduction: extrasystole, atrial fibrillation, paroxysmal tachycardia,
atrioventricular blockade, etc. The development of arrhythmias is based on two main electrophysiological mechanisms:
1) ectopic automatism and 2) circular circulation of the excitation wave due to the reverse input of the impulse. Both pathogenetic mechanisms indicate that the
hierarchy in the control of the heart muscle is violated: individual parts of the myocardium go out of the control of the overlying structures (sinus-atrial node)
and begin to work independently.
