Brief Summary
This is a prospective and observational study. The investigator speculated that the use of DC in patients with paroxysmal AF can serve as a predictor for early and late AF recurrence following CPVI.

Interventions
Circumferential pulmonary vein isolation (CPVI) is a type of cardiac ablation procedure. Cardiac ablation procedures involve creating small scars in the heart using thermal or cold energy to block irregular electrical signals and restore normal heart rhythm. CPVI specifically creates small scars in the area where the four pulmonary veins connect to the left atrium of the heart. The pulmonary veins carry oxygen-rich blood from the lungs to the heart.
Eligibility Criteria
Patients undergoing CPVI due to paroxysmal atrial fibrillation.
You may qualify if:
- Sign the informed consent form;
- Clearly diagnosed as paroxysmal AF, willing to receive CPVI treatment;
- A class I or class III antiarrhythmic drug with poor efficacy, or intolerance to drugs.
You may not qualify if:
- Diagnosis of sinus rhythm at recruitment;
- Age is \<18 years old or\> 75 years old;
- Transthoracic echocardiography suggested a left atrial anterior and posterior diameter of\> 55mm;
- Previous history of catheter ablation or surgical ablation for AF;
- Left atrial thrombus recorded by ultrasound or CT;
- With severe pulmonary diseases;
- Previous history of cardiac surgery;
- Patients with hyperthyroidism, atrial septal defect, mitral valve stenosis or severe coronary heart disease who need further treatment;
- During pregnancy or lactation.
