交感型颈椎病对心率变异性频谱的影响

Effects of sympathetic cervical spondylosis on heart rate variability

【目的】探讨交感型颈椎病对心率变异性频谱的影响。【方法】利用短程频谱分析法检测31例交感型颈椎病患者及年龄、性别相匹配的26例健康对照组不同体位(静卧,静立,静坐)时的心率变异性频谱。【结果】(1)交感型颈椎病激惹型组(22例)不同体位时的平均心率(MHR)、低频(LF)成分及LF/HF比值明显高于对照组,具有显著性差异(P<0.05);而两组间高频(HF)成分比较差异无显著性(P>0.05)。(2)交感型颈椎病麻痹型组(9例)不同体位时的MHR及HF值明显低于对照组,具有显著性差异(P<0.05);而两组间LF/HF及LF值分别比较,差异无显著性(P>0.05)。【结论】本研究能为心脏,神经、骨科等,跨学科研究交感型颈椎病提供非侵入性诊断和鉴别诊断方法。综合分析心率变异性频谱可对交感型颈椎病的诊断和鉴别诊断提供敏感、可靠的客观定量指标。

【Objective】The purpose of the research is to study the effects of the sympathetic cervical spondylosis（C.S） on heart rate variability.【Methods】31 patients with sympathetic C.S and 26 healthy controls with metched age and sex were examined by short-term frequency spectrum analysis.【Results】（1）There were significant differences between sympathetic nevous exciting group（22 out of 31 patients）and the controls on the score of MHR,LF and LF/HF in supine,sitting and standing positions（P〈0.05）,but no significant differences between both groups（P〉0.05）;（2）The scores of MHR and HF in supine,sitting and standing positions of paralysis group（9 out of 31） of sympathetic C.S had significant differences of both groups（P〈0.05）.The scores of LF/HF and LF had no significant differences between both groups（P〉0.05）.【Conclusions】We hope that this study would support an interdisciplinary research for medicine,neurology,orthopaedics and so on,which could be used as one of the non-invasive method to diagnose and differtiate the sympathetic C.S.The short-term frequency heart rate variability spectrum analysis provide reliable indicators for the study on the cardiac symptoms of sympathetic cervical spondylosis.
