Wolff-Parkinson-White Syndrome (WPW) describes an arrhythmia caused by an electrical activity trapped in a circular pattern.
A form of congenital heart defect known as Wolff-Parkinson-White Syndrome appears when an additional portion of heart muscle creates a different electrical conduction pathway between your heart's upper and lower chambers. Then, both the additional pathway and the regular pathway are used by your heart's electrical impulses. This makes the heart beat fast because it forces the impulses to move quickly and in a circular manner around the heart.
