摘　　要：目的探讨高刺激率听性脑干诱发电位和眼震视图对后循环缺血性眩晕患者的诊断价值。方法对64例临床确诊为后循环缺血(posterior circulation ischemia,PCI)患者行H-ABR、VNG检测,并与45例正常受试者相应检测结果对照。结果 PCI患者H-ABR检测64例中异常52例,异常率达81.2%;51次/s-11次/s的Ⅰ-Ⅴ波间潜伏期的差值(△IPL)>0.30、VNG检测结果不同程度的异常,与对照组受试者比较差异具有统计学意义(P<0.05)。结论 H-ABR、VNG同步检查有助于PCI的诊断。Objective To study the clinical value of high stimulation rate auditory brainstem response （H-ABR） and visual nystagmography （VNG） in the diagnosis of posterior circulation isehemic vertigo （PCIV）. Methods H-ABR and VNG were performed in 64 cases with clinically-confirmed PCIV and 45 normal aduhs. Their results,were analyzed statistically. Results H-ABR revealed abnormal results in 52 of the 62 PCIV patients with an abnormal rate of 81.2%. The difference of the interpeak latency intervals from wave I to V between 51 times/s to 11 times/s was greater than 0.30. VNG test also showed abnormality to different degree. All the results of the PCIV group were statistically different from those of the control group. Conclusion Synchronized H-ABR and VNG may facilitate the diagnosis of PCIV.
