We report on the first direct comparison of measures of seizure quality generated by visual rating of electroencephalographic (EEG) regularity and postictal suppression with THYMATRON-DGx computer-generated indices of seizure energy and postictal suppression. Thirty-two consecutive patients referred for electroconvulsive therapy (166 consecutive treatments) were studied. Blinded ratings of seizure duration, regularity, and postictal EEG amplitude suppression derived from the paper EEG were compared against computer-rated measures of seizure duration, seizure energy index, mean ictal amplitude, and postictal suppression. Our results confirm previous findings of high correlations between computer and visual determinations of seizure duration. Significant differences were found for computer-derived postictal suppression, seizure energy index and mean ictal amplitude for different levels of the visual rating scales. Our results provide preliminary support for the concurrent validity of these measures.
我们报告了首次直接比较通过脑电图（EEG）规律性的视觉评分和发作后抑制所产生的癫痫发作质量指标与THYMATRON-DGx计算机生成的癫痫发作能量和发作后抑制指标。对连续32例接受电休克治疗的患者（共166次连续治疗）进行了研究。将来自纸质脑电图的癫痫发作持续时间、规律性和发作后脑电图振幅抑制的盲法评分与计算机评定的癫痫发作持续时间、癫痫发作能量指数、平均发作期振幅和发作后抑制指标进行了比较。我们的结果证实了先前关于计算机和视觉判定癫痫发作持续时间之间高度相关性的发现。对于视觉评分量表的不同水平，在计算机得出的发作后抑制、癫痫发作能量指数和平均发作期振幅方面发现了显著差异。我们的结果为这些指标的同时效度提供了初步支持。
