Does ablation affect the presence of early repolarization in patients with Wolff-Parkinson-White syndrome?
In patients with WPW syndrome, early repolarization often persists or appears newly after ablation, indicating that mechanisms beyond accessory pathway depolarization contribute to its genesis.
In patients with WPW syndrome, ER could be partly related to early depolarization through the accessory pathway. However, persistent ER and new ER appearing after the ablation were frequently found. Therefore, in these patients, mechanisms other than early depolarization may be involved in the genesis of ER.
Mizumaki et al. (Wed,) studied this question.
