Ictal bradycardia followed by cardiac asystole: a case report Volume 4, numéro 4, December 2002


   
  

Figure 1. a. Interictal EEG showing diffuse theta slow waves and eye movements artifacts.

Figure 1. b. Seizure onset: theta activity in the left temporal region increasing in frequency and amplitude followed by rapid involvement of the contralateral hemisphere.

Figure 1. c. Continuation of the seizure: diffuse rhythmic delta activity associated with tachycardia.

Figure 1. d. End of the seizure: post-ictal EEG abnormalities including diffuse theta and delta sloww aves mainly in the left temporal region. The electrocardiogram shows a slowing down of cardiac rhythm.

Figure 1. e. A fewseconds after ictal bradycardia, a sinus arrest lasting 10.6 s is observed. Concomitant EEG shows a flattening of cerebral activity.








   
   Figure 1. f. Recovery of cardiac rhythm with persistent flattening of cerebral activity, lasting 7 s.

Figure 1 (continued). g. Post-ictal EEG associated with tachycardia.
