Wolff-Parkinson-White Syndrome is a rare disorder involving irregularities in the heartbeat (cardiac arrhythmia). Patients have an extra circuit or pathway, called the Bundle of Kent, through which electrical signals are conducted to the heart, allowing excessive stimulation. Palpitations (sensation of rapid or irregular beating of the heart), weakness, and shortness of breath may occur.
These arrhythmias frequently stop spontaneously or with simple maneuvers but may require taking medications daily if they persist.
