Abstract
The Wolff-Parkinson-White (WPW) syndrome is characterized by an accessory pathway (by-pass tract) between the atria and ventricles that conducts parallel with the atrioventricular (AV) node-His bundle, but faster (Wolff, Parkinson, & White, 1930; Yee, Klein, & Guiraudon, 1995). An accessory AV connection can conduct in both directions. The presence of these bypass tracts may predispose to atria-ventricular reentrant tachycardia. Moreover, in the setting of atrial fibrillation, the WPW syndrome may cause a catastrophically rapid ventricular response with degeneration to ventricular fibrillation (VF).
