Arrhythmogenic seizures.

Arrhythmogenic seizures may represent one of the mechanisms implicated in sudden unexpected death in epilepsy. Various cardiac changes can be observed during epileptic seizures. However, reports of well-documented, life-threatening cardiac arrhythmias in the literature are scarce. The pathogenesis of these arrhythmias and speculations about the cortical localization of cardioarrhythmogenic triggers are reviewed.
