Summary: Little is known about bradycardia and cardiac asystole which occur during partial epileptic seizures, especially whether they relate to ictal involvement of well‐defined cortical areas. Several reports based on simultaneous electro‐cardiographic and intracranial depth electroencephalographic monitoring have shown that either the fronto‐orbital cortex or the amygdalohippocampal complex could be responsible for such cardiac variations. We performed stereo‐EEG recordings in a patient with refractory localization‐related epilepsy associated with a hypo‐thalamic hamartoma. We found that other cortical areas, such as the frontocentral region and the temporal neocortex, can contribute to the genesis of ictal bradyarrhythmia. Second, the lesion per se, although located within the hypothalamus, is not involved with this phenomenon.
