Abstract

Distinguishing abnormal electroencephalogram (EEG) waveforms from benign variants is critical for accurate interpretation of EEG. Hyperventilation (HV) is one of the basic procedures during EEG to enable activation of epileptiform activity. Rarely, HV can activate benign EEG rhythms. Herein, we illustrate two pediatric cases with bursts of rhythmic mid-temporal theta of drowsiness (RMTD), activated by hyperventilation. Continued awareness of this EEG phenomenology and its variations in pediatrics is important in avoiding misdiagnosis of epilepsy.

摘要

区分异常脑电图（EEG）波形与良性变异对于准确解读脑电图至关重要。过度换气（HV）是脑电图检查中的基本操作之一，可促使癫痫样活动的激活。极少数情况下，过度换气可激活良性脑电图节律。在此，我们展示两例小儿病例，其困倦期节律性中颞区θ波爆发（RMTD）由过度换气激活。持续了解这种脑电图现象及其在儿科中的变化对于避免癫痫误诊很重要。
