Catheter Ablation

Catheter ablation is the generally preferred first-treatment method for many types of arrhythmias that are difficult to treat with medications. It causes little discomfort and is performed under mild sedation with local anesthesia.

One or more catheters are threaded through the blood vessels to the inner heart and positioned along electrical pathways suspected of causing the arrhythmia. Electrodes at the catheter tips are heated with radiofrequency energy, which destroys (ablates) a small spot of heart tissue and creates an electrical block along the pathway causing your arrhythmia. Radiofrequency catheter ablation is most commonly used to treat:

  • AV nodal reentry tachycardia
  • Atrial fibrillation and atrial flutter
  • Accessory pathways
  • Ventricular tachycardia

Physicians associated with Providence Arrhythmia Services perform complex atrial fibrillation ablations in our Electrophysiology Labs including:

  • Imaging equipment using fluoroscopy
  • RF generator + stimulator
  • Digital Imaging
  • Intracardiac Echocardiography
