Wolff-Parkinson-White syndrome is the name for episodes of fast heart rate caused by an extra electrical pathway between the atria and the ventricles. The fast heart rate often occurs because the electrical impulses go down one pathway from the atria to the ventricles and then return to the atria through the other pathway.
