[Clinical use of transvenous electrodestruction of the atrioventricular junction in patients with supraventricular tachyarrhythmia].
The authors described 51 patients with different types of supraventricular tachyarrhythmias and ciliary arrhythmia paroxysms who showed resistance to drug therapy. All the patients were treated by the closed transvenous electrodestruction of the atrioventricular junction by producing a series of discharges with a defibrillator to the area of His' bundle, the power being 280-400 J. A stable and complete transversal blockade was obtained in 45 patients, in 6 patients the restoration of permeability in the atrioventricular system with frequent ventricular responses was observed, being the reason for repeated electrodestructions. No complications were observed. In the patients with blockade of the I-II degree tachycardia paroxysms either stopped or were milder and subjected to drug therapy. Biologically controlled electrocardiostimulators of the "demand" type were implanted to all patients after electrodestruction of the atrioventricular junction. Proceeding from the above the authors made a conclusion that the closed transvenous electrodestruction was a method of choice in the treatment of supraventricular tachyarrhythmias and ciliary arrhythmia paroxysms who showed resistance to drug therapy. It can be effectively used for seriously ill patients and elderly persons.
