摘要
目的 :观察直立调节障碍患者的自主神经功能状况 ,评价交感神经皮肤反应 (SSR)在晕厥鉴别诊断中的应用价值。方法 :对 32例直立调节试验阳性的晕厥患者 (病例组 )进行电刺激SSR检测 ,并以 32例健康志愿者作对照。结果 :病例组SSR潜伏期延长 (1 5 4± 0 2 8s) ,波幅降低 (1 16± 0 33mV) ,与对照组SSR潜伏期 (1 36± 0 2 1s)和波幅 (1 87± 0 5 9mV)相比差异均有显著性意义 (P <0 0 1)。结论 :直立调节障碍患者存在交感神经功能障碍 ,在晕厥的鉴别诊断中 ,SSR是一种有实用价值的神经电生理方法。
Objective: To observe the autonomic function in patients with orthostatic adjustment disorder and to evaluate the application value of the sympathetic skin response(SSR) in the differential diagnosis of syncope.Methods: SSR was determined by electrical stimulation in 32 patients with positive orthostatic adjustment test and 32 normal volunteers were served as controls.Results:SSR latency was prolonged(1.54±0.28*!s)and the amplitude was increased(1.16±0.33*!mV) in patient group.In control group,SSR latency was 1.36±0.21*!s,amplitude was 1.87±0.59mV.A significant difference was noted in both latency and amplitude as compared with the normal subjects(P<0.01).Conclusion:A sympathetic nerve disfunction might be found in patients with orthostatic adjustment disorder.SSR might be a neurophysiological method of practical value in the differential diagnosis of syncope.
