Overview

• Somewhere between 0.1 and 3 per 1000 EKGs.
• May be underdiagnosed given the presence of left sided APs which may be silent during NSR.
• The incidence of tachyarrhythmias in patients with WPW has been estimated to be somewhere between 12% and 80%.
• WPW may be the most prevalent cause of paroxysmal regular supraventricular tachycardia One series found that 57% of patients c psvt were subsequently found to have WPW syndrome on the resting NSR EKG. If the attack occurs before the age of 21, then 73% of the patients had WPW. In patients > 21 years old, then WPW syndrome was found in 48% of patients with PSVT. (Wellens et al 1981).
