Fig. 1

Electrocardiogram of one of the patients. The prominent S wave in lead I and R wave in aVR demonstrate the T40-ms rightward axis shift (255°) [16]. The ECG also shows an incomplete RBBB.

Fig. 1

Mean seizure duration for each response group. This demonstrates that phenytoin does not control febrile seizures frequently (n = 9 episodes), but failure to respond to phenytoin (n = 28 episodes) leads to significantly more prolonged seizures.
