目的:研究动态心电图在评价2型糖尿病患者心脏自主神经功能中的价值。方法:选择2012年2月~2015年2月在我院进行诊治的2型糖尿病患者260例,按照心血管自主神经功能分为损伤组152例和正常组108例,采用动态心电图检查两组的心率变异、心脏变时功能不全和心率震荡。结果:两组间平均心率相比无明显差异(P>0.05),损伤组的最慢心率明显高于正常组(P<0.05),最快心率和差值明显低于正常组(P<0.05);两组间震荡初始无明显差异(P>0.05),损伤组的震荡斜率明显低于正常组(P<0.05);损伤组的窦性心搏间期均值的标准差、相邻R-R间期差值的均方根值和5 min心搏间期均值的标准差均明显低于正常组(P<0.05)。结论:应用动态心电图检测心脏变时性功能不全指标和心率震荡、心率变异指标能准确评价2型糖尿病患者的心脏自主神经功能,具有较高的诊断价值。
Objective: To study the value of ambulatory electrocardiogram in evaluating cardiac autonomic nervous system function in type 2 diabetic patients. Methods: From February 2012 to February 2015 in our hospital for diagnosis and treatment of type 2 diabetes in 260 cases, according to cardiovascular autonomic function is divided into injury group 152 cases and normal group 108 cases, the use of dynamic electrocardiogram examination of two groups Heart rate variability, heart dysfunction and heart rate turmoil. Results: The average heart rate was not significantly different between the two groups (P> 0.05). The slowest heart rate in the injury group was significantly higher than that in the normal group (P <0.05), and the fastest heart rate and difference were significantly lower than those in the normal group ). There was no significant difference in initial shock between the two groups (P> 0.05), and the oscillation slope of the injury group was significantly lower than that of the normal group (P <0.05). The standard deviation of sinus beat interval mean The standard deviation of rms value and mean heart rate at 5 min were significantly lower than those in normal group (P <0.05). CONCLUSION: Using the dynamic electrocardiogram to detect the indexes of cardiac dysfunction and heart rate turbulence, heart rate variability index can accurately evaluate the cardiac autonomic nervous function in patients with type 2 diabetes mellitus, which has high diagnostic value.
