What is the most common cause of SVT?

Can SVT cause a stroke?

What are the risks of SVT ablation?

Risks and complications

Stroke. Heart attack. Death. Damage to the heart or lungs requiring surgery.

How is life after SVT ablation?

Most people see improvements in their quality of life after SVT ablation. But there's a chance the fast heartbeat may return. If this happens, the procedure may be repeated or your health care provider might recommend other treatments.

Simple but specific actions such as coughing, bearing down as if having a bowel movement or putting an ice pack on the face can help slow down the heart rate. Your health care provider may ask you to do these actions during an episode of SVT . These actions affect the vagus nerve, which helps control the heartbeat.
