Intervention

Other:
• a dual energy catheter (RF and PFA) or PFA catheter only will be to treat PeAF,Cardiac Pulsed Electric Field Ablation Catheter
This study will be used two catheters, the contact force sensing catheter able to deliver both RF and PFA energy, this catheter provides both the radiofrequency (RF) energy and pulsed field ablation (PFA) energy to the catheter through the toggling of the two energy sources on the generator monitor. Another catheter is PFA catheter only.
• catheter ablation

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Immediate success rate	Refers to the proportion of the number of subjects electrically isolated in each AF patient after surgery to the total number of subjects enrolled.	1 Day of catheter ablation
Secondary	Ablation success at 3-month after the catheter ablation	Ablation success is defined as no recurrence with no anti-arrhythmic drugs by taking history of symptoms from the patient and by Holter 24 Hours.	3 months
