Does the Policy of Repeated Early Cardioversion for Recurrences of Atrial Fibrillation Work?
Atrial fibrillation (AF) is a very common arrhythmia, which increases in prevalence in patients more than 60 years old. Over time, it tends to become persistent or permanent, even if no underlying structural heart disease is present. The success rate of electrical cardioversion and the maintenance of sinus rhythm are highly dependent on the duration of the previous AF episode. After electrical cardioversion only 20%–40% of patients maintain sinus rhythm for the first year . The highest incidence of recurrences is seen during the first month after cardioversion, particularly within the first 5 days, when AF recurs in up to 40% of patients .
