title: [Effect of atrio-ventricular conduction on the appearance of supraventricular arrhythmia and thrombotic complications in patients with chronic stimulation of cardiac ventricles in sick sinus syndrome].
abstract: Two hundred three patients with sick sinus node disease were treated with continuous ventricular stimulation between 1981 and 1985. To 1988, 168 patients aged between 26 and 88 years were followed-up for 5.1 years on the average. All these patients were divided into two groups: I (93 patients) with sinusal bradycardia, and group II (93 patients) with brady-tachycardia. Ventriculo-atrial conduction was seen in 82.61% of patients of group I in whom the implantation of electric stimulator produced the attacks of atrial fibrillation, and in 44.23% of patients without such attacks (p < 0.01); in 80.77% of patients of group II in whom atrial fibrillation became stable with time, and in 50.57% with intermittent atrial fibrillation (p < 0.01) ventriculo-atrial conduction was noted. It may be concluded, that the presence of ventriculo-atrial conduction in patients with prolonged stimulation of the cardiac ventricles favor the occurrence and stabilization of the paroxysmal atrial fibrillation and thrombotic complications.
