[Electric stimulation of the heart in disorders of atrio-ventricular conduction and paroxysmal supraventricular tachycardia in patients with sick sinus syndrome].
Continuous atrial (73) or ventricular (77) electrostimulation, alone or combined with transvenous endocardial electrodestruction of the AV junction (24) was performed in 150 patients with sick sinus syndrome (SSS). Five-year follow-up of 148 patients identified groups of patients with impaired atrioventricular conductivity and bradytachy-arrhythmic SSS syndrome. Prolonged atrial electrostimulation is shown to be possible in cases of moderately impaired atrioventricular conductivity. Antiarrhythmic efficiency of atrial and ventricular electrostimulation was found to be insufficient for the prevention of atrial fibrillation paroxysms. It is concluded that transvenous electrodestruction of the atrioventricular junction in combination with ventricular electrostimulation is highly effective in cases of bradytachy-arrhythmic SSS syndrome. Surgical strategy is proposed for different types of the SSS syndrome.
