Detection of atrial vulnerability by transesophageal atrial pacing and the relation of symptoms in children with Wolff-Parkinsonwhite Syndrome and in a symptomatic control group

Abstract In pediatric patients with a structurally normal heart, atrial fibrillation (AF) is a rare arrhythmia. 1–3 In children with Wolff-Parkinson-White (WPW) syndrome, AF at electrophysiologic study can be induced in 20% to 50% of patients. 4−5 This present study determines if the atria of pediatric patients with WPW are more vulnerable to AF than those of pediatric patients without WPW using transesophageal atrial pacing (TAP) to induce the AF.
