Medically Reviewed on 9/10/2019

Wolff-Parkinson-White syndrome is an abnormality of the electrical system of the heart, which transmits signals that coordinate the heartbeat. WPW syndrome and pre-excitation syndrome are other names for Wolff-Parkinson-White syndrome. Doctors usually identify it in children or young adults.

Signs and symptoms associated with Wolff-Parkinson-White syndrome include a fast heart rate, irregular heart rate, palpitations, dizziness, lightheadedness, and shortness of breath. A characteristic pattern on an electrocardiogram (ECG) is a sign of the condition. The symptoms typically come on suddenly without warning. Caffeine, exercise, and consumption of alcohol can all be triggers that cause a racing heart in people with Wolff-Parkinson-White syndrome.
