ECG monitoring during and after the epileptic seizures showed a progressive prolongation of RR intervals (A) with a subsequent sinus bradycardia (< 30 beats/min) (B) followed by asystole lasting 8 s (C), spontaneously returned to normal sinus rhythm of 80 beats/min (D).

Immediately after the epileptic seizure, the ECG revealed sinus bradycardia (< 30 beats/min) (Figs. 1A and B) followed by asystole lasting 8 s and hypotension (70/40 mm Hg) (Fig. 1C), spontaneously returning to normal sinus rhythm of 80 beats/min (Fig. 1D) with normalization of blood pressure.
Baseline electroencephalogram (EEG), performed a few days later, showed dominant 7 Hz sub-alpha activity admixed with slower elements (theta rhythm: 4-6 Hz) prevailing in frontocentral right regions, sometimes with spike morphologies. EEG conclusion: specific electrographic abnormalities in frontocentral areas, with basic activity deregulated and slowed.

Baseline EEG, performed a few days later, was abnormal, showing dominant 7 Hz sub-alpha activity admixed with slower elements (theta rhythm: 4-6 Hz) prevailing in frontocentral right regions, sometimes with spike morphologies (Fig. 2).
