  • o The most recent electrocardiogram must be within 180 days of enrollment.
  • NOTE: Documented evidence of the AF episode must either be continuous AF on a
  • 12-lead ECG or include at least 30 seconds of AF from another ECG device.
  • 2. Plans to undergo a PVI catheter ablation procedure due to symptomatic PAF or
  • PersAF and is refractory, intolerant, or contraindicated to at least one Class
  • I-IV AAD medication
  • 3. At least 18 years of age
  • 4. Able and willing to comply with all trial requirements including
