摘　　要：目的:研究高刺激率ABR检测与眩晕反复发作的相关性,探讨眩晕反复发作的病因,为眩晕反复发作的临床诊疗提供重要的帮助。方法:回顾性分析反复眩晕的患者101例,分别观察比较眩晕反复发作患者发作期和间歇期与高刺激率ABR之间的关系。结果:反复眩晕患者发作期多次(2次及其以上)出现高刺激率ABR异常率为56.4%,其中偏头痛性眩晕出现的异常率最高,达到71.9%,良性阵发性位置性眩晕次之;用药期间或发作间歇期多次出现高刺激率ABRⅠ～Ⅴ潜伏期差值异常的患者占总例数的14.9%,各眩晕组出现异常的比率较之发作期都有明显下降。结论:高刺激ABR异常率与眩晕反复发作具有显著的相关性,内耳微循环障碍可能是引发眩晕反复发作的主要原因之一。Objective：To study the relevance of the high stimulus rate auditory brainstem response（auditory brainstem response,ABR） test in recurrent vertigo,investigate the cause of recurrent vertigo,and provide important help for the clinical treatment.Method：One hundred and one cases with recurrent vertigo were retrospectively analyzed,and high stimulus rate ABR were tested and compared in attack episodes and intermittent episodes.Result：The abnormal difference between ABR ⅠandⅤ latency was selected as parameters.The abnormal rate of high stimulation ABR was 56.4% in patients with recurrent episodes of vertigo many times（2 and above）,of which the highest rate was 71.9% in MV patients,and the second one was BPPV.The abnormal rate of high stimulation ABR was 14.9% in patients during medication or intermittent episodes.The abnormal rate in all groups decreased obviously as compared to attack episodes.Conclusion：Abnormal rate of high stimulus rate ABR correlates well with recurrent vertigo significantly.The inner ear microcirculation may result in the attack of recurrent vertigo.
