Supraventricular Tachycardia Ablation
Overview
What is Supraventicular Tachycardia Ablation?
Supraventicular tachycardia (SVT) ablation is a procedure used to treat abnormal heart rhythm (arrhythmias) in your heart’s upper chambers that cause abnormally fast or erratic heartbeat. The procedure uses extreme cold, lasers, or radiofrequency energy, to create tiny scars in your heart tissue to block abnormal electrical signals that are causing your arrhythmia. The goal of SVT ablation is to prevent your arrhythmias, reduce your symptoms and the need for heart rhythm medications, and improve the quality of your life.
Why
Why Supraventicular Tachycardia Ablation?
Your doctor may recommend SVT ablation if medication or other treatments do not work, or if you have atrial flutter or atrial tachycardia.

What to Expect
What to Expect During a Supraventicular Tachycardia Ablation
During the Procedure
SVT ablation is done in the hospital and takes between 2 to 4 hours. Here’s what you can expect during the procedure:
- You’ll be given a sedative to help you relax, and the groin area where the catheter will be inserted will be prepared.
- Your doctor will numb your groin area and will carefully thread the catheter into your heart.
- Sensors at the tip of the catheter record your heart’s electricity and show your doctor the best place to apply the ablation treatment.
After the Procedure
- After the procedure is over, your doctor will gently remove the catheter and bandage the insert site.
- You will then go into recovery to monitor your vital signs before you are discharged with your doctor’s instructions.
