目的 :为明确变异型慢α波的生理或病理意义。方法 :采用日本三荣 1A94型脑电图机 ,按准 10 /2 0系统放置 16个电极 ,常规描记脑电图 ,结果与临床病史、体征及实验室诊断作对照分析。结果 :14例均无明确相关的病理意义。结论 :变异型慢α波属生理波 Objective: To clarify the physiological or pathological significance of the slow alpha wave of variant. Methods: Sanyei 1A94 EEG machine was used in this study. Sixteen electrodes were placed on the standard 10/20 system. EEG was performed routinely. Results were compared with clinical history, signs and laboratory diagnosis. Results: All the 14 cases had no definite pathological significance. Conclusion: Variant slow alpha wave is a physiological wave
