Wolff-Parkinson-White syndrome

Wolff-Parkinson-White syndrome is an abnormal electrical connection (or bypass tract) between the atria and ventricles of the heart. The bypass tract allows electricity in the heart to travel abnormally fast and results in a very rapid heart rate (arrhythmia).

Symptoms of Wolff-Parkinson-White syndrome include the sense of feeling the heart beat rapidly (palpitations), light-headedness, fainting, and dizziness.
