The association between partial seizures and cardiac asystole has rarely been reported in the literature.
This potentially life-threatening symptom has been observed principally in left-sided epilepsies, in particular during seizures originating in temporal lobe. We describe a case with ictal bradycardia followed by cardiac asystole during right frontal lobe seizures.
Video-EEG monitoring recorded two partial seizures with electro-clinical findings suggestive of a right frontal lobe origin, associated with ictal bradycardia followed by prolonged asystole. The
brain MRI showed a lesion located in the cingulate gyrus of the right frontal lobe. The patient required a subsequent placement of a pacemaker. In conclusion, cardiac asystole may be a potentially life-threatening symptom during seizures of frontal lobe origin. The right fronto-mesial structures may play a role in autonomic regulation of cardiovascular responses.
