What types of cardiac arrhythmias can catheter ablation treat?

Ravi K. Sureddi, MD
Clinical Cardiac Electrophysiology
A variety of heart rhythm problems are treatable by catheter ablation. In this video, Ravi K. Sureddi, MD, a cardiac electrophysiologist at Riverside Community Hospital, describes those conditions, including atrial fibrillation.
Catheter ablation can potentially treat all forms of inappropriate fast heart rhythms, whether they occur in the upper chambers (atria) or lower chambers (ventricles). Ablation therapy is not useful in the treatment of slow heart rhythms or arrhythmias due to heart block (not to be confused with blockage in a heart artery), where pacemaker therapy is more likely to be an appropriate therapy.

The following are arrhythmias that can be treated with catheter ablation (and their causes):
  • AV nodal reentrant tachycardia (extra pathway in or next to AV
  • Accessory pathway (extra pathway in tissue bridge that connects
           atria to ventricles)
  • Atrial tachycardia (abnormal circuit in right or left atrium)
  • Atrial flutter (abnormal circuit in right atrium)
  • Atrial fibrillation (several pathways usually in left atrium)
  • Inappropriate sinus tachycardia (abnormal high rate from the sinus
            node) and
  • Ventricular tachycardia (abnormal circuit in the right or left ventricle)
Catheter ablation can treat several types of cardiac arrhythmias, including:

  • AV nodal reentrant tachycardia (AVNRT);
  • Accessory pathway;
  • Atrial fibrillation and atrial flutter;
  • Ventricular tachycardia.
