Why the study?
Does rapid atrial pacing prior to shock reduce the atrial defibrillation threshold in patients with atrial fibrillation undergoing internal cardioversion?
Population
11 patients with atrial fibrillation undergoing internal cardioversion
Comparison
Rapid atrial pacing immediately followed by a… vs Biphasic defibrillation shock only
Design
RCT, randomized, crossover design

Pre-shock rapid atrial pacing does not reduce atrial defibrillation threshold; challenges the hypothesized benefit and does not support clinical use.
Does rapid atrial pacing prior to shock reduce the atrial defibrillation threshold in patients with atrial fibrillation undergoing internal cardioversion?
Rapid atrial pacing prior to shock does not significantly lower the atrial defibrillation threshold during internal cardioversion for atrial fibrillation.
Frykman et al. (2003) studied this question.
