摘要
目的 为交感神经型颈椎病的诊断和治疗提供一项新的无创性量化诊断标准。方法 应用 2 4h动态心电图测定 2 5例交感神经型颈椎病患者的心率变异指标 ,并分白天和夜间 2个时段与 2 5例年龄、性别配对的正常人比较。结果 交感神经型颈椎病和对照组MHR、MeanRR(白天时段 )、LF/HF 3项指标比较无显著性差异 (P >0 .0 5 ) ;其余 2个时段指标Mean RR(夜间时段 )、SDNN、SDANN、rMSSD、PNN50 两组相比较 ,颈椎病组明显降低 (P <0 .0 5 )。病例组 2个亚型间心率变异性 (Heartratevariability ,HRV)分析指标比较表明 ,激惹型与麻痹型MHR、MeanRR、LF/HF有显著性差异 (P <0 .0 5 )。 5 0例受检者的Lorenz散点图表明 ,慧星状、非慧星状 2组构成比差异有非常显著意义 (χ2 =2 6 .0 87,P <0 .0 1)。结论 交感神经型颈椎病患者心率变异性降低 ,表明植物神经功能受损 ,其中颈交感神经激惹型患者交感神经张力升高 ,颈交感神经麻痹患者交感神经张力降低 ,该型患者迷走神经功能也有部分受损。此结论为交感神经型颈椎病患者的治疗提供了客观和量化参数。
Objective To provide a new non invasive quantitative index for diagnosis of sympathetic nervous cervical spondylosis.Mehtods The heart rate variability of 25 patients with sympathetic nervous cervical spondylosis were measured by dynamic electrocardiography,divided into day time groups and night time groups,and compared with those of 25 normal individuals.Results There was no significant difference in MHR,mean RR (day time ) or LF/HF between the patients and the normal individuals (P>0.05),but the difference in mean RR ( night time),SDNN,SDANN,rMSSD and PNN 50 was (P<0.05).Meanwhile,there was significant difference in MHR,mean RR and LF/HF between the paralytic cervical spondylosis and the irritable cervical spondylosis.The Lorenz scatter diagrams of 50 cases indicated that the difference in constituent ratio between cometic and imcometic diagram was very significant (P<0.01).Conclusions The heart rate variability in patients with sympathetic nervous cervical spondylosis is decreased.It will probabaly provide an objective and numeral index for the diagnosis of sympathetic nervous cervical spondylosis
