Abstract
Electrophysiologic testing in patients with asymptomatic Wolff-Parkinson-White syndrome (WPW) may be useful in defining arrhythmic substrates and predictors of fatality. Forty-two patients with asymptomatic WPW, mean age 36 years, underwent electrophysiologic studies and were followed prospectively. They were compared with a matched control group of patients studied within the same period for documented tachycardia associated with the WPW syndrome. Asymptomatic patients had longer anterograde effective refractory periods of the accessory pathway, longer minimum cycle lengths maintaining 1:1 conduction over the accessory pathway, longer minimum RR intervals between consecutive preexcited beats during atrial fibrillation (AF) and longer mean RR intervals during AF than their symptomatic counterparts. Sustained reciprocating tachycardia could not be induced in most patients and induction of AF required rapid atrial pacing in all patients. Nine patients had an anterograde effective refractory period of less than 270 ms and 17% had minimum cycle length less than 250 ms during induced AF. Over a follow-up of 29 ± 18 months, 1 patient died of noncardiac causes and the rest remained asymptomatic. Thus, patients with asymptomatic WPW have deficient electrophysiologic substrates to maintain orthodromic reciprocating tachycardia under baseline conditions and do not have atrial vulnerability. Seventeen percent of patients had potentially lethal ventricular rates during induced AF.
