分析了１８０例发作性疾病患者临床发作与２４ｈ动态脑电图异常脑电发放的时相关系，存在三种情况：异常放电与临床发作时相一致；时相不一致及发作与发作间期均无异常放电。９３．３％的患者明确了诊断类别；９３％的癫痫确定了发作类型。讨论了动态脑电图对发作性疾病的诊断价值及异常放电、癫痫及非癫痫之间的相互关系。 Analysis of 180 cases of seizures in patients with clinical seizure and 24 hours EEG abnormal EEG release of the phase relationship, there are three situations: abnormal discharge and clinical seizure phase consistent; inconsistency between the time and seizure episodes were Abnormal discharge. 93.3% of patients identified the diagnostic category; 93% of epilepsy identified the type of attack. The diagnostic value of dynamic electroencephalogram (EGE) for paroxysmal disease and the relationship between abnormal EEG, epilepsy and non-epilepsy were discussed.
