[Bradycardia: an unrecognized complication of some epileptic crises].

A 36-year-old man, treated for epilepsy since early childhood, was hospitalized for nocturnal paroxysmal disorders. The EEG-EKG-video monitoring revealed complex partial seizures with bradycardia secondary to a sino-auricular block. The occurrence of autonomic disturbances during seizures is well known, mostly described in temporal epilepsy. Ictal bradycardia, with asystole, has been unfrequently reported, while tachycardia appears more common. A systematic investigation of cardiac data synchronized with EEG recordings, especially in case of aspecific fainting, could give a more accurate diagnosis and treatment, and so reducing sudden unexplained death in epileptic patients.
