Syncope vs. Seizure: Ictal Bradycardia and Ictal Asystole

Figure 1

During the synchronous recording of electroencephalography (EEG) and echocardiogram (ECG) using bipolar montages (double banana), the patient experienced a left temporal seizure and asystole. The ECG lead showed a complete AV block emerging in the pink lead, and the arrow indicated an 18-second asystole on the ECG lead at the end of the seizure. The ECG gradually returned to normal sinus rhythm afterwards.
