Overview
Brief Summary
The purpose of this study is to verify the safety and efficacy of the cardiac pulse ablation system in paroxysmal atrial fibrillation to provide the basis for product registration and clinical application.
The trial will be conducted at a clinical center with appropriate clinical cases, and paroxysmal atrial fibrillation ablation procedures will be performed by an authorized investigator using the trial product. The effectiveness and safety of the cardiac pulse ablation system in the treatment of paroxysmal atrial fibrillation will be verified by collecting the treatment success rate, immediate ablation success rate, procedure time and device use evaluation within 12 months after the procedure.

Outcomes
Primary Outcomes
Rate of Treatment Success at 12-Month Post-Procedure
Time Frame: Refers to the postoperative phase (blank) after 12 months postoperatively
Refers to the postoperative phase (blank) after 12 months follow-up after process, without the use of class I and class III anti-arrhythmic drugs, by ECG, Holter, or Heart rate monitoring method based on equivalent (including a single lead electrocardiogram) confirmed that there are no last 30 s or af/the room/speed events account for the number of participants into the group of the proportion of the total number.
Rate of Treatment Success at 3-Month Post-Procedure
Time Frame: Refers to the postoperative phase (blank) after 3 months postoperatively
Refers to the postoperative phase (blank) after 3 months follow-up after process, without the use of class I and class III anti-arrhythmic drugs, by ECG, Holter, or Heart rate monitoring method based on equivalent (including a single lead electrocardiogram) confirmed that there are no last 30 s or af/the room/speed events account for the number of participants into the group of the proportion of the total number.
Rate of Treatment Success at 6-Month Post-Procedure
Time Frame: Refers to the postoperative phase (blank) after 6 months postoperatively
Refers to the postoperative phase (blank) after 6 months follow-up after process, without the use of class I and class III anti-arrhythmic drugs, by ECG, Holter, or Heart rate monitoring method based on equivalent (including a single lead electrocardiogram) confirmed that there are no last 30 s or af/the room/speed events account for the number of participants into the group of the proportion of the total number.
Secondary Outcomes
- Immediate success rate: pulmonary vein isolation after ablation(1 Day of surgery)
- Evaluation of Pulse Ablation Catheter(1 Day of surgery)
- Evaluation of Pulse Ablation equipment(1 Day of surgery)
