Seven-hour (7-h) video-encephalography (VEEG) on admission. (A) Background activity slowed down, mainly with theta (θ) wave. (B) The left frontal pole, frontal, central, midfrontal line, and central region of the spike-slow wave discharged. (C) Multiply spike-slow wave; multispike-slow wave; the slow wave is covered with spine and spikes, cluster or rhythmic discharge in both hemispheres. (D) Atonic seizures. The transient electrical rest appeared 20–40 ms in electromyography (EMG) after electroencephalogram (EEG) synchronous spike-slow wave burst. The clinical manifestations are head droop. X5: left upper limb; X6: left upper limb; X7: ECG; SEN: 20 uV; HF: 70; TC: 0.3; the red arrow is the electric rest.
