The authors themselves studied 26 patients. The EEGs were classified in terms of increasing severity in 5 categories. Incorporating over 400 cases from the literature, the authors correlated the initial EEG findings with the clinical outcome following cardiac arrest. Grade I EEG findings (normal alpha with theta-delta activity) imply a very good prognosis. A complete remission can be expected in most cases. Grade II (dominant theta-delta activity with detectable normal alpha) and grade III (dominant theta-delta activity without detectable normal alpha) findings have no definite prognosis. Grade IV [low-voltage delta, possibly with short isoelectric intervals; dominant, monomorphic, non-reactive alpha-activity (alpha coma); periodic generalized phenomena (spikes, sharp waves, slow waves with very low background activity)] and grade V (very flat to isoelectric EEG) findings have a very serious prognosis.
作者本人研究了26例患者。脑电图根据严重程度增加分为5类。作者纳入了文献中的400多例病例，将心脏骤停后的初始脑电图结果与临床结局进行了关联。I级脑电图结果（正常α波伴θ-δ活动）预示预后非常好。大多数情况下可预期完全缓解。II级（占主导的θ-δ活动伴可检测到的正常α波）和III级（占主导的θ-δ活动，无可检测到的正常α波）结果无明确预后。IV级[低电压δ波，可能伴有短等电位间期；占主导的、单形的、无反应的α波活动（α昏迷）；周期性全身性现象（棘波、尖波、背景活动极低的慢波）]和V级（脑电图非常平坦至等电位）结果预后非常严重。
