Findings of electronystagmography (ENG) in 645 patients with vertigo were analysed. Two hundred and twelve cases showed vestibular peripheral vertigo, 394 cases vestibular central vestigo, and 39 cases other types of vertigo. The ENGs in patients with vestibular peripheral vertigo were charazterized mainly by the vestibular abnormal caloric responses, spontaneous and benign positional nystagmuses were also obsedrved at the same time. Different degrees and various combinations of the abnormal responses shown in optokinetic central test were the most characteristic of ENG in patients with vestibular central vertigo. The results suggest that ENG is particularly useful for differentiating peripheral and central vertigo.
对645例眩晕患者的眼震电图（ENG）检查结果进行了分析。其中212例表现为前庭周围性眩晕，394例为前庭中枢性眩晕，39例为其他类型眩晕。前庭周围性眩晕患者的ENG主要表现为前庭冷热试验异常反应，同时还可观察到自发性和良性位置性眼震。视动中枢试验中出现的不同程度及多种异常反应组合是前庭中枢性眩晕患者ENG最具特征性的表现。结果表明，ENG对鉴别周围性和中枢性眩晕特别有用。
