[The use of AF SUPRESSION pacing algorithm in supression of paroxysmal atrial fibrillation in patients with bradycardia--one center experience].

Heart pacing with algorithms preventing episodes of paroxysmal atrial fibrillation (PAF) is one of the modern methods of PAF treatment. The usefulness of AF suppression TM pacing algorithm in Integrity AFx DR pacing was evaluated. The study group consisted of 7 patients with paroxysmal AF (for average 2,5 year; requiring on average 6 cardioversions in ICCU per year) and standard pacemaker indications. The small number of enrolled patients resulted from high cost of the pacemaker. In our study we turned on AF suppression TM pacing algorithm 3 months after pacemaker implantation and evaluated the number of PAF episodes at 3 and 6 months. Pharmacotherapy was not changed. Antiarrhythmic stimulation resulted in reduction of the number of PAF (on average by 11) at 3 months and was well-tolerated by the patients. AF Suppression(tm) pacing algorithm is effective only if PAF is preceded by supraventricular extrasystole.
