Wolff-Parkinson-White syndrome
Alternate Names : Preexcitation syndrome, WPW
Definition
Wolff-Parkinson-White syndrome is a heart condition in which there is an extra electrical pathway (circuit) in the heart. The condition can lead to episodes of rapid heart rate (tachycardia). Wolff-Parkinson-White is one of the most common causes of fast heart rate disorders in infants and children.
Overview, Causes, & Risk Factors
Normally, electrical signals in the heart go through a pathway that helps the heart beat regularly. The wiring of the heart prevents extra beats from occurring and keeps the next beat from happening too soon. In people with Wolff-Parkinson-White syndrome, there is an extra, or accessory, pathway that may cause a very rapid heart rate. This is called supraventricular tachycardia.
