Summary
EEG is useful to make prognostic estimations and evaluate for nonconvulsive seizures post cardiac arrest. Unfavorable EEG patterns portend poor outcomes, whereas early improvements including restoration of physiological rhythms are associated with better outcomes. The EEG has limitations; it should not be used in isolation to make prognostic estimations. Highly malignant EEG patterns are specifically associated with poor outcomes. Individual malignant patterns have low sensitivity and specificity for poor outcomes. Benign patterns (absence of malignant features) suggest favorable outcomes. Seizures and status epilepticus are common post cardiac arrest and may contribute to poor outcomes. Myoclonic status epilepticus is characterized by prolonged cortical myoclonus. Early myoclonic status epilepticus post cardiac arrest is typically associated with poor prognosis.
