title: Early repolarization and its modification by preexcitation in two patients with intermittent Wolff-Parkinson-White syndrome.
abstract: We report two cases of intermittent Wolff-Parkinson-White (WPW) syndrome. In one patient, early repolarization (ER) was masked during preexcitation whereas in the other, J wave-like notches were observed in the right precordial leads only during preexcitation. The clinical significance of ER is not apparent in WPW syndrome but some possible mechanisms are discussed.
