DISEASE INTERVENTION COMPARISON RESULTS
Scand Cardiovasc J. 2003 Dec;37(6):324-8 Randomized Controlled Trial
IN StudyID: Dahlin 2003, atrial fibrillation, natural history, frequency of recidive The Use of
electrical cardioversion, not followed by antiarrhythmics
As Treatment, Chronic

To maintain sinus rhythm at long-term: only 13% of patients at 1 year

elective electrical cardioversion
As Treatment, Acute

To restore sinus rhythm in 75% patients. At 4 weeks only 37% of patients maintained sinus rhythm. Duration of AF < 3 months and right atrial dimension < 37 mm were independent predictors of maintaining SR
