Catheter Ablation Procedures for Supraventricular Tachyarrhythmias (SVTA)

Catheter ablation is a procedure used to treat some types of heart arrhythmias, most commonly those tachyarrhythmias that originate above the ventricles. These SVTAs can be categorized by the origin of the tachyarrhythmia.

  • Atrial tachyarrhythmias initiate within the atrium:
    • sinus tachycardia,
    • atrial tachycardia,
    • macroreentrant atrial tachycardia (i.e., atrial flutter), and
    • atrial fibrillation.
  • Atrioventricular tachyarrhythmias originate within the atrioventricular (AV) node or the surrounding area:
    • AV nodal reentrant tachycardia,
    • AV reentrant tachycardia, which includes Wolf-Parkinson-White Syndrome,
    • focal junctional ectopic tachycardia, and
    • nonparoxysmal junctional tachycardia.                           

Catheter ablation is typically performed in a catheter lab and involves guided insertion of catheters from the arm, groin, or neck through the blood vessel and into the heart.
