目的探讨糖尿病对心脏植物神经功能的影响。方法用立位反射的立卧位心率差（Ｂ－Ａ）、立卧位时心率比值（Ｂ／Ｃ），深呼吸时心搏间距变化（ＨＲＶ）及眼心反射３种方法４个指标对２６例糖尿病患者，进行心脏植物神经功能检测分析。结果糖尿病组Ｂ－Ａ、Ｂ／Ｃ、ＨＲＶ、眼心反射的异常率与正常对照组相比，有显著性差异（Ｐ＜０．０１）。糖尿病组中，ＨＲＶ、Ｂ／Ｃ、眼心反射异常率明显高于Ｂ－Ａ异常率（Ｐ＜０．０１）。结论糖尿病对患者心脏植物神经功能有损害，以迷走神经为主。
Objective To investigate the effect of diabetes on cardiac autonomic function. Methods Three indexes of vertical reflection (B-A), heart rate ratio (B / C) in vertical position, heart rate change (HRV) Cases of diabetic patients, cardiac autonomic nerve function test analysis. Results The abnormal rates of B-A, B / C, HRV and ocular reflex in diabetic group were significantly different from those in normal control group (P <0.01). In the diabetic group, HRV, B / C and ocular reflex abnormalities were significantly higher than those of B-A abnormalities (P <0.01). Conclusion Diabetes has impaired cardiac autonomic function in patients with predominantly vagus nerve.
