ABSTRACT
Antidromic: Conduction occurs antegrade through the accessory path, then retrograde through the atrioventricular node. This results in prominence of the delta wave and a widened QRS complex. This is less common than orthodromic conduction
• Most common cause of sudden death in patients with WPW syndrome is atrial fibrillation with rapid ventricular response that may degenerate into lethal ventricular fibrillation
