B-po04-194 pediatric t-wave memory after accessory pathway ablation in wolff-parkinson-white syndrome

Wolff-Parkinson-White (WPW) syndrome leads to altered ventricular depolarization, secondary to ventricular preexcitation, which in turn leads to repolarization abnormalities that can persist after pathway ablation. The term T-wave memory has been applied to these changes, as the post-ablation T-wave vector “remembers”, and often mirrors, the preexcited QRS vector. In adults, these T-wave abnormalities can be misinterpreted as ischemia, leading to unnecessary evaluation and intervention. The role of T-wave memory in children remains unknown.
