对脑电图的过度解读是一个已知问题，但尚未具体报告。作者报告了一系列最终被诊断为心因性非癫痫发作且脑电图显示为癫痫样发作的患者的脑电图。在可供审查的 15 条实际记录中，被重读的模式是三柱门峰值 (n = 1)、下位超同步 (n = 1) 和过度换气引起的减慢 (n = 1)。在其他 12 条记录中，重读模式是轮廓清晰的背景节奏的简单波动或活动的碎片化。过度解释的模式往往是背景活动的正常波动，而不是充分描述的正常变异。
The overinterpretation of EEGs is a known problem that has not been reported specifically. The authors report a series of EEGs on patients who were diagnosed eventually with psychogenic nonepileptic seizures and who had an EEG read as epileptiform. Of the 15 actual records available for review, the overread patterns were wicket spikes (n = 1), hypragogic hypersynchrony (n = 1), and hyperventilation-induced slowing (n = 1). In the other 12 records, the overread patterns were simple fluctuations of sharply contoured background rhythms or fragmented a activity. Rather than well-described normal variants, the overinterpreted patterns tend to be normal fluctuations of background activity.
