From January 1983 to May 1992 a total of 40 patients with a tachysystolic type of atrial flutter (AF) refractory to preventive antiarrhythmic therapy were examined and operated on. The obligatory stage of a preoperative examination was invasive phonoelectrocardiography. The effects of "entrainment" and adaptation of refractory periods of various portions of atria were estimated depending on the duration of a basic stimulation cycle.

The article analyses the late-term results of operations on 46 patients for paroxysms of supraventricular tachyarrhythmias (SVTA) which were refractory to prophylactic administration of antiarrhythmics. Transvenous electrodestruction of the atrio-ventricular junction were carried out in 39 patients. The results were good in 34 and satisfactory in 3 patients; conductivity and paroxysms reappeared in 2 patients.
