Medicine such as adenosine, antiarrhythmic drugs, and amiodarone may be used to control or prevent a rapid heartbeat.
If the heart rate does not return to normal with medication, doctors may use a type of therapy called electrical cardioversion (shock).
The long-term treatment for Wolff-Parkinson-White syndrome is catheter ablation. This procedure involves inserting a tube (catheter) into an artery through a small cut near the groin up to the heart area. When the tip reaches the heart, the small area that is causing the fast heart rate is destroyed using a special type of energy called radiofrequency.
Open heart surgery to burn or freeze the extra pathway may also provide a permanent cure for Wolff-Parkinson-White syndrome. However, surgery is usually done only if you need surgery for other reasons.
