Summary

This study explored the influence of radiofrequency catheter ablation and cryoballoon ablation on atrial electrical remodeling in patients with atrial fibrillation,the relationship between atrial electrical remodeling and structural remodeling,and which indicators are associated with atrial recurrence after catheter ablation.

Conditions

Interventions

PROCEDURE

radiofrequency ablation or cryoballoon

Patients in radiofrequency ablation group receive circumferential pulmonary vein isolation,and no additional ablation is performed in the extrapulmonary sites unless the patient is diagnosed with atrial flutter before the operation. And Cryoablation is performed using a single cryoballoon. The diameter of the cryoballoon is determined as 28 mm or 23 mm according to pulmonary venography results.
