Ictal Asystole During Focal Seizures Due to Left Occipital Glioneuronal Tumor: A Report of Case Treated With Cardiac Neuromodulation

Online ahead of print.ABSTRACTIctal asystole (IA) is a rare but potentially life-threatening complication of focal epilepsy. The sudden onset of loss of consciousness and drop attacks in a patient with chronic epilepsy should suggest the possibility of this complication. Once the diagnosis is established, rapid management should be considered, especially in high-risk cases. The approach does not differ between temporal and extratemporal lobe epilepsies. Strategies can be aimed at preventing the emergence of cortical epileptic activity from the beginning (surgery, antiseizure therapy), neutralizing negative chronotropic effects on the heart (cardiac neuromodulation), or restarting the heart rhythm with a pacemaker. Pacemaker implantation is not a completely complication-free treatment, and living with a device that requires care and follow-up throughout life makes alternative treatment methods more valid for young patients with many years to live or cases that could benefit from surgery. In this article, we present a patient with a left occipital glioneuronal tumor and drug-resistant occipital lobe epilepsy. IA was documented by long-term video EEG monitoring (VEM). During about 2 years of follow-up after a cardiac neuromodulation procedure, there were no drop attacks or asystole with seizures, confirmed by long-term VEM.PMID:38403965 | DOI:10.1177/15500594241234831
