Total atrio-ventricular block during epileptic seizures, especially those of temporal origin, may be a possible explanation for sudden unexpected death in epilepsy (SUDEP).
Alerts clinicians to monitor for ictal AV block in temporal epilepsy; single case leaves open its role in SUDEP.
Tigaran S, Mølgaard H, Dam M. Atrio-ventricular block: a possible explanation of sudden unexpected death in epilepsy. Acta Neurol Scand 2002: 106: 229–233. © Blackwell Munksgaard 2002 Introduction– This is the third case report describing the occurrence of total atrio-ventricular (AV)-block as a life threatening cardiac arrhythmia complicating epileptic seizures. Case report– A 56-year-old right-handed man was admitted to our hospital for surgical assessment of his medically intractable epilepsy. During the hospitalization he was enrolled in a study investigating cardiac complication of epileptic seizures as the possible cause of sudden unexplained death among epileptics. Discussion– To the best of our knowledge, we are the first to employ simultaneous video-electroencephalogram-, Holter- and pulse oximetry-recordings of our patients in the description of this complication. These recordings allowed us to discuss the evidence and consequences of this particular cardiac abnormality as an explanation of sudden unexplained death in epileptic seizures, especially those of temporal origin.
