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

将异常脑电图（EEG）波形与良性变异区分开来对于准确解释EEG至关重要。过度通气（HV）是EEG期间激活癫痫样活动的基本程序之一。很少,HV可以激活良性脑电节律。在这里，我们说明了两个儿科病例，有节奏的中颞θ嗜睡（RMTD），被过度换气激活。对这种脑电图现象学及其在儿科中的变化的持续认识对于避免癫痫的误诊很重要。
