Video-EEG of Case 1. A 16-channel EEG was used with the associated ECG strip demonstrating sinus arrest and asystole lasting for 47 seconds. During asystole, brief convulsive movements and tonic posturing of her body are observed and myoclonic activity is seen with restoration of sinus rhythm. Note "slow-flat-slow" pattern of EEG (generalised slowing, followed by generalised suppression and generalised slowing again). The sound has been muted as requested by the patient.
