Description. Wolff-Parkinson-White (WPW for short) is a syndrome in which pre-excitation of the ventricles can occur due to impulses traveling through an accessory pathway in the heart from the atria to the ventricles. The arrow in the diagram below points to an area of the heart where this may typically occur.
