Hoekstra, MD, University Hospital (Groningen, The Netherlands) on behalf of the RACE investigators reported that long-term maintenance of sinus rhythm was significantly reduced by the side effects of sotalol and amiodarone and the discontinuation amiodarone, but not by clinical characteristics. They suggested that the high incidence of side effects from the drugs is responsible for the failure of rhythm control to show superiority over rate control for the treatment of atrial fibrillation (AF), as reported in several large randomized trials. The current analysis was designed to determine the actual number of AAD side effects, their clinical characteristics, and relation of the side-effects to the failure of long-term maintenance of sinus rhythm in the 266 patients with AF (/= 1 risk factor for stroke.2 PB - Indian Pacing and Electrophysiology Group KW - Latest Updates In EP TI - Latest Updates In EP AV - public ER -
