title: [Prophylaxis of atrioventricular block in surgery of reentry tachycardia].
abstract: Experience of treatment of 85 patients with reentry tachycardia of atrioventricular node was analyzed. In 10 patients (first group) dottal applications directed from coronary sinus ostium toward atrioventricular bundle (AVB) were applied; in 75 (second group)--from the tricuspid valve ring deep inside atrium on the coronary sinus ostium. Temporary disorder of atrioventricular conductivity of different degree was observed in 3 patients of first group and in 1--of the second group, in whom applications were plotted in the middle of distance between coronary sinus ostium and AVB. In one observation several commissures were situated between electrocardiograms of atrium and ventriculus, not permitting to reveal trustworthy the presence of AVB potential.
