轻微椎—基底动脉供血不足性眩晕相当多见,确诊常有困难。我们三年来用法国产RACIA—77B型眼震电仪,对本病进行了眼震电图检查,获得了有诊断价值的资料,鉴于国内此类报导较少,故将检查结果总结报导如下: 病例选择本组选择病例共110人(男65人,女45人),年龄19～71岁,均经神经内科检查确诊:眩晕多因头位或(和)体位变动诱发,呈旋转感(23例,20.9％)或视物晃动不稳感(54例,49.1％),或两者兼有(32例,30％);眩晕同时恒伴有其他脑干一过性缺血症状,绝大多数有轻微脑干损害体症;部份患者脑血流图或脑电图转颈后描记,枕部波幅明显下降,或脑干听觉诱发电位提示脑干异常;有的既往史中有其他椎—基底动脉或颈动脉系统缺血发作;有的有原发病变的 Vertebral - basilar insufficiency vertigo quite common, often diagnosed with difficulties. We use France RACIA-77B type of nystagmus three years, the disease was examined by electronystagmography, access to diagnostic data, in view of the domestic such reports are less, so the test results are summarized as follows: Case Select this group of patients selected a total of 110 people (65 men and 45 women), aged 19 to 71 years old, were diagnosed by neurology examination: dizziness and more due to head position or () position induced changes were rotational sense (23 cases , 20.9%) or unsteady visual acuity (54 cases, 49.1%), or both (32 cases, 30%); vertigo accompanied by other brainstem transient ischemic symptoms, the vast majority There is a slight damage to the brain stem body disease; some patients with cerebral blood flow or EEG electrocardiogram neck tracing, occipital amplitude decreased significantly, or brainstem auditory evoked potentials prompted brain stem abnormalities; some previous history of other vertebral - Basilar artery or carotid system ischemic attack; some have primary lesions
