Wolff-Parkinson-White (WPW) syndrome is a condition in which episodes of fast heart rate (called tachycardia) occur because of an abnormal extra electrical pathway in the heart. People with WPW may experience palpitations, dizziness, lightheadedness, and fainting, although some people with WPW have no symptoms.
The prevalence rate for chronic Wolff-Parkinson-White syndrome has been estimated as 10% per 60,000.
Medicines, particularly antiarrhythmic drugs such as procainamide or amiodarone, may be used to control or prevent a rapid heartbeat.
Researchers at the British Heart Foundation are working on several treatment options for Wolff-Parkinson-White syndrome.
