Wolff-Parkinson-White (WPW) syndrome is a heart rhythm problem that causes a very fast heart rate. WPW is one type of supraventricular tachycardia called atrioventricular reciprocating tachycardia (AVRT). With WPW, an extra electrical pathway links the upper chambers (atria) and lower chambers (ventricles) of the heart.
