Brief summary
Compare the safety and efficacy of remote magnetic navigation-guided ablation and cryoablation for patients with persistent atrial fibrillation.
Detailed description
1. Compare the efficacy of remote magnetic navigation-guided ablation and cryoablation for patients with persistent atrial fibrillation. 2. Compare the safety of remote magnetic navigation-guided ablation and cryoablation for patients with persistent atrial fibrillation. 3. Compare the procedural parameters of remote magnetic navigation-guided ablation and cryoablation for patients with persistent atrial fibrillation. 4. Compare the effects of amiodarone on recurrence after these two different ablation procedures.
Interventions
