摘　　要：６４５例眩晕患者的眼震电图检查结果：属前庭周围性眩晕２１２例，前庭中枢性眩晕３９４例，其它原因和原因不明３９例。前庭周围性眩晕患者眼震电图检查主要为前庭温度试验异常，同时伴闭眼自发性眼震和良性位置性眼震。前庭中枢性眩晕患者的眼震电图特点是不同程度和不同组合的视动中枢试验异常。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.
