(A-D) Awake ictal EEG. Seizureonset characterized by background flattening over the left temporal region (large blue arrow), followed by a fast recruiting activity (small blue arrow); the latter is difficult to see because of muscular artifact covering the brain activity. Subsequently, a medium-high-amplitude polymorphic and rhythmic theta-delta activity over the antero-mesial left hemisphere appears (large orange arrows). After 30 seconds, a medium-amplitude monomorphic and rhythmic fast activity over temporal electrodes is observed (red arrow), with which a clear change of both associated ipsi- and contralateral hemispheric activity (horizontal red line). At the end of this last recruiting discharge, the activity preceding it returns over the antero-mesial left hemisphere (small orange arrows) and after four seconds, cardiac arrest occurs (green arrow). After 10 seconds from the cardiac arrest, a widespread EEG suppression appears (red star) and after another 14 seconds, the cardiac rhythm reappears (green arrow). Fourteen seconds after cardiac rhythm recovery, the brain background activity reappears (violet star).
