分析比较MS、DM、高血压患者及正常对照组的HRV。结果:MS与DM,高血压一样,SDNN、SDANN、SDNNindex、ULF、VLF、LF及HF均较正常组降低,差异有统计学意义(P<0.05)。结论(1)MS、糖尿病、高血压患者HRv降低,交感及迷走神经同时受损,自主神经调节失衡;(2)MS、DM及高血压时HRV均隆低,对心血管疾病有一定的预测作用。 Analysis and comparison of HRV in MS, DM, hypertensive patients and normal control group. Results: MS, like DM and hypertension, were significantly lower than those of normal group (P <0.05). SDNN, SDANN, SDNNindex, ULF, VLF, LF and HF were lower than those of normal group. Conclusions (1) The HRv of MS, diabetes mellitus and hypertension patients are decreased, the sympathetic and vagal nerve are impaired at the same time, the regulation of autonomic nerve is unbalanced; (2) The HRV of MS, DM and hypertension are both low, which may have some predictive effects on cardiovascular diseases .
