Catheter ablation is used to treat abnormal rapid heart rhythms that arise from specific circuits in the heart. After an EP study locates the source, a catheter delivers radiofrequency or cryothermal energy to destroy the small area of abnormal tissue.
It is effective for:
- Supraventricular tachycardia (SVT)
- Atrial flutter or fibrillation
- Ventricular arrhythmias in selected cases
This minimally invasive procedure often eliminates the need for medications.
