Summary

Electrical/pharmacological cardioversion improves structural remodeling of left atrium. We hypothesize that persistent atrial fibrillation (AF) patients with more significant left atrial size reduction after cardioversion have lower AF recurrence rates following radiofrequency ablation. The aim is to evaluate the relationship between changes in left atrial size 3 to 6 months after cardioversion and the recurrence rate of atrial fibrillation following radiofrequency ablation.
