Key result
Transesophageal atrial pacing accurately identifies multiple accessory pathways and tachycardia forms in pediatric WPW syndrome.
Why the study?
Arrhythmia induction and identifying functional characteristics of accessory pathways in Wolff-Parkinson-White syndrome typically requires an invasive electrophysiological study.
Does transesophageal atrial pacing effectively identify accessory pathways in a pediatric patient with Wolff-Parkinson-White syndrome?

Does transesophageal atrial pacing effectively identify accessory pathways in a pediatric patient with Wolff-Parkinson-White syndrome?
Transesophageal atrial pacing is a potentially effective, minimally invasive diagnostic tool for evaluating accessory pathways in pediatric patients with Wolff-Parkinson-White syndrome.
May support transesophageal pacing as a diagnostic option in pediatric WPW; hypothesis-generating and requires validation before clinical adoption.
Arrhythmia induction and identifying the functional characteristics of accessory pathways in Wolff-Parkinson-White (WPW) syndrome typically requires an invasive electrophysiological study. This case reports a 13-year-old boy with a five-year history of paroxysmal palpitations, where transesophageal atrial pacing (TEAP) was used to identify accessory pathways. TEAP revealed multiple tachycardia forms, differentiating orthodromic atrioventricular reentrant tachycardia with narrow and wide QRS complexes. EPS confirmed two pathways, diagnosing WPW syndrome. TEAP effectively assessed accessory pathways' functional characteristics and their roles in tachycardia, showcasing its potential as a minimally invasive diagnostic tool for this condition.

Chen et al. (2025) conducted a case report in Wolff-Parkinson-White (WPW) syndrome (n=1). Transesophageal atrial pacing (TEAP) vs. Invasive electrophysiological study (EPS) was evaluated on Identification of accessory pathways and their functional characteristics. Transesophageal atrial pacing effectively identified multiple tachycardia forms and accessory pathways in a 13-year-old boy with WPW syndrome, which was subsequently confirmed by invasive EPS.
