Temporal dynamics of EEG patterns associated with generalized myoclonus after cardiopulmonary resuscitation

Introduction: There is only limited knowledge on the temporal dynamics of EEG patterns associated with generalized myoclonus (GM) after cardiopulmonary resuscitation (CPR). Methods: We examined 100 consecutive comatose survivors of CPR with GM occurring within 24 hours, when the first EEG was done (=day 1). Subsequent EEGs were recorded in all surviving patients at day 2, and between days 3 and 4, days 5 and 6, and days 7 and 8. Results: GM was mainly associated with a burst-suppression EEG (BS-EEG) (n=67), or continuous generalized epileptiform discharges (CGED) (n=21). The remaining patients had areactive alph…
