Pediatric T-wave memory after accessory pathway ablation in Wolff-Parkinson-White syndrome

Altered ventricular depolarization due to manifest accessory pathway conduction, Wolff-Parkinson-White syndrome, leads to repolarization abnormalities that persist after pathway ablation. The term T-wave memory (TWM) has been applied to these changes, as the post-ablation T-wave vector “remembers” the preexcited QRS vector. In adults, these abnormalities can be misinterpreted as ischemia leading to unnecessary interventions. To date, there have been no comprehensive studies evaluating this phenomenon in the pediatric population.
