By analyzing the collected data, the initial safety and efficacy of the electrode catheter ablation effect of the clinical trial medical device is evaluated. After the clinical trial, the initial safety and efficacy of the electrode catheter ablation are evaluated by analyzing the changes in electrical signals before and after the procedure and by monitoring patients.
The goal of this clinical trial is to evaluate the initial safety and effectiveness of an investigational medical device.~Electrode catheter ablation of the Marshall vein is performed using TIRA, a clinical trial medical device for patients with persistent atrial fibrillation,
