Electroencephalogram findings from resuscitated patients after cardiac arrest. (A) Electroencephalogram (EEG) recorded during therapeutic hypothermia, showing an example of continuous EEG: the patient had complete recovery of consciousness. (B) Burst-suppression findings during normothermia; the patient had concomitant myoclonus and bilateral absent N20 cortical responses to somatosensory evoked potentials, and eventually died. (C) Generalized periodic epileptiform discharges at 36 hours after hospital admission; we decided to withdraw care on day 5 because of persistent coma with posturing and absent pupillary reflexes.
