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. (PACE 2012; 35:e231–e233)
