Comparison of clinical and electrophysiological characteristics between ictal and cardiac asystole encountered during video-EEG monitoring Volume 21, issue 4, August 2019

Figure 1

VEM findings of Patient 3 (see supplementary table 1) (24-channel EEG with one channel of simultaneous ECG recorded with high frequency filter = 70 Hz, low frequency filter = 0.5 Hz, sensitivity = 10 μV/mm, and display speed = 30 mm/sec): (A) ictal onset characterized by a burst of multiple spikes followed by rhythmic spikes over the right posterior temporal region with phase reversal at T6, as illustrated by the red arrow; (B) onset of asystole after a latency of 24.1 seconds following the ictal EEG onset; and (C) diffuse slowing with attenuation of activity and asystole offset.
