Radiofrequency ablation is indicated in the following patients:

  • Patients with symptomatic AVRT
  • Patients with AF or other atrial tachyarrhythmias that have rapid ventricular response via an accessory pathway (preexcited AF)
  • Patients with AVRT or AF with rapid ventricular rates found incidentally during EPS for unrelated dysrhythmia, if the shortest preexcited RR interval during AF is less than 250 ms [4]
  • Asymptomatic patients with ventricular preexcitation whose livelihood, profession, insurability, or mental well-being may be influenced by unpredictable tachyarrhythmias or in whom such tachyarrhythmias would endanger the public safety [5]
  • Patients with WPW and a family history of sudden cardiac death
