Phase 2

In patients with persistent atrial fibrillation recurrence after atrial fibrillation ablation without pulmonary venous reconduction, we evaluated the effectiveness of ablation using spatiotemporal dispersion electrograms (STDE) visualized using a fractionation map. A single-center prospective randomized study evaluating the low voltage zone (LVZ) visualized by voltage map compared to ablation (ARCHERY study)

Eligibility Criteria

Inclusion Criteria

  • 1\. patients over 18 years of age
  • 2\. Patients undergoing a second catheter ablation for recurrent persistent AF after initial pulmonary vein isolation
  • 3\. Patients who have given their consent to participate in this study by signing a consent form in person.

Exclusion Criteria

  • 1\. patients with AF arrest at the time of EPS
  • 2\. patients with no STDE at the time of EPS
  • 3\. patients with pulmonary veins (PV) re\-conduction at the time of EPS
  • 4\. patients with allergy or serious renal disorder that precludes pre\- and post\-operative contrast\-enhanced cardiac CT
