Medicines, particularly antiarrhythmic drugs such as procainamide or amiodarone, may be used to control or prevent a rapid heartbeat.
If the heart rate does not return to normal with medical treatment, doctors may use a type of therapy called electrical cardioversion (shock).
The long-term treatment for Wolff-Parkinson-White syndrome is very often catheter ablation. This procedure involves inserting a tube (catheter) into a vein 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 or by freezing it (cryoablation).
Open heart surgery to burn or freeze the extra pathway may also provide a permanent cure for Wolff-Parkinson-White syndrome. In most cases, this procedure is done only if you need heart surgery for other reasons.
