[Elimination of drug-resistant supraventricular tachyarrhythmia by transvenous electrodestruction of the atrioventricular junction].

The authors report on the first successful employment of transvenous electrodestruction of the atrio-ventricular junction in patients with supraventricular tachyarrhythmias resistant to the drug and electroimpulse therapy. The procedure of transvenous electrodestruction in six patients consisted in making a discharge of 250-350 J from a stationary R-synchronized defibrillator in the area of the compact atrio-ventricular node or the proximal portion of the His bundle. All patients were implanted R-banning ECS-222 Li. The follow-up period after the operation varied from 2 to 6 months. The patients reported no disturbances in cardiac performance and palpitation over this period.
