All recorded seizures had a clear onset at the left temporal region (maximum at F7 and T3) (Fig. 1). For focal seizures that generalized, the focal portion lasted approximately 10 s followed by 60 s of generalized activity (Fig. 1).
Title: EEG showing ictal bradycardia.. 15 s after seizure onset, severe bradycardia develops and continuous changes at the left sphenoidal electrode can be seen (bipolar montage).
