Wolff-Parkinson-White syndrome [1] (sometimes referred to as Wolfe Parkinson White or WPW) is a syndrome of pre-excitation of the ventricles of the heart due to an accessory pathway known as the bundle of Kent. [2] This accessory pathway is an abnormal electrical communication from the atria to the ventricles. The incidence of WPW syndrome is between 0.9 and 3% of the general population.
