Ablation of Anisochronous Zones vs Spatio-temporal Dispersal Zones With Antral Electrical Isolation During Radiofrequency Treatment of Paroxysmal or Persistent Atrial Fibrillation

Comparison of Ablation of Anisochronous Zones vs Spatio-temporal Dispersal Zones in Addition to Antral Electrical Isolation During Radiofrequency Treatment of Paroxysmal or Persistent Atrial Fibrillation

Using isochronous maps during radiofrequency ablation procedures may identify the driver zones responsible for atrial fibrillation maintenance with greater accuracy compared to a conventional procedure (simple antral isolation of the associated pulmonary veins or, if necessary, combined with removal of spatio-temporal dispersal zones) that do not use isochronous maps, and thus improve the efficiency and safety of atrial fibrillation treatment by radiofrequency treatment.
