title: Coexistence of triphasic waves and alpha-coma pattern.
abstract: The coexistence of triphasic waves and alpha-coma pattern in an EEG was observed in a 67-year-old comatose man following cardiopulmonary arrest, while his brain stem functions were intact. Although they may be diagnostically and prognostically significant, these EEG findings can be hard to recognize. These two distinct EEG patterns do not seem to be mutually exclusive.
