MAX - SHOCK Clinical Trial

Recruiting now · Not applicable

Conditions studied: Cardioversion, Atrial Fibrillation

In brief

Can Electrical Cardioversion (ECV) for AF be improved. It is the preferred method to restore sinus rhythm in patients with AF in whom a rhythm-control strategy is pursued. Hypothesis: ECV success rates will be greater with a biphasic defibrillator with maximum energy of 360J (® Physio-Control) compared to a biphasic defibrillator with maximum energy of 200J (® Zoll)
