In pathological conditions, the role of the pacemaker can be performed by other areas of the heart, rather than with [[rhythm driver sinus|sinus rhythm driver]]. Muscle cells of the heart generate impulses by themselves, without any external influences (automata). The sinus-atrial node suppresses all lower sections of the conducting system by more frequent pulses, but if it is damaged by the pacemaker, the atrioventricular node, which generates pulses with a frequency of 40-50 per minute, can become a rhythm driver. | In pathological conditions, the role of the pacemaker can be performed by other areas of the heart, rather than with [[rhythm driver sinus|sinus rhythm driver]].
