Brady-tachy syndrome: rapid atrial pacing efficacy in preventing atrial fibrillation recurrence assessed by reliable electrograms: the prefib pilot study.

Aims: Recent studies have tested different atrial pacing rates, modes, and sites for preventing atrial fibrillation (AF) recurrence. Present generation pacemakers offer reliable electrograms (EGMs) storage for optimizing the arrhythmia diagnosis. Based on these EGMs, the study objective was to assess the rate of AF recurrence at two different pacing rates.
