Does long-acting quinidine improve the maintenance of sinus rhythm in patients with DC converted sustained atrial fibrillation?
Prophylactic treatment with long-acting quinidine significantly reduces the relapse rate of atrial fibrillation at 3 months and 1 year following DC cardioversion compared to no treatment.
No takes yet. Share an insight, caveat, or question.
Quinidine prophylaxis after DC cardioversion reduces AF relapse; confirms antiarrhythmic benefit for sinus rhythm maintenance in RCTs.
Boissel et al. (1981) studied this question.
