DC cardioversion supports acute restoration in permanent atrial arrhythmias; cohort data leaves open optimal long-term maintenance strategies.

Does DC shock treatment improve reversion to sinus rhythm in patients with permanent atrial arrhythmias?
DC shock is highly effective for the initial reversion of permanent atrial arrhythmias (80% success), though long-term maintenance of sinus rhythm is lower (23% at 2 years) and anticoagulation appears to reduce embolic complications.
Bjerkelund et al. (1968) conducted an observational in Permanent atrial arrhythmias (n=437). DC shock treatment was evaluated on Reversion to sinus rhythm during the first attempt. DC shock treatment successfully reverted permanent atrial arrhythmias to sinus rhythm in 80% of patients during the first attempt, with 23% maintaining sinus rhythm at two years.
