糖尿病患者动态心电图改变及临床意义

目的 探讨糖尿病患者动态心电图的改变及临床意义.方法 随机选取60例糖尿病患者,另取50例健康者为对照组（两组无年龄、性别统计学差异）,对比观察动态心电图指标（心率、心律、HRV、SDNN、RMSSD、PNN50、LF、HF、LF/HF、ST-T）改变.结果 糖尿病组心率较对照组显著增快（P＜0.05）;糖尿病组心率变异指标较对照组明显降低（P＜0.05）;各种心律失常及ST-T发生率糖尿病组也明显高于对照组（P＜0.01）.结论 糖尿病患者心律失常发生率明显增高,HRV显著降低,心脏迷走神经损伤明显;动态心电图检查对于预测糖尿病患者合并神经及心脏受损有显著意义.

The Change and Clinical Value of Dynamic Electrocardiogram in Patients with Diabetes Mellitus

Objective To explore the change and clinical value of dynamic electrocardiogram in pa tients with diabetes mellitus（DM）. Methods Two contrast groups contained random sampling of 60 patients with DM and 50 healthy cases （no statistics differences on age and gender） ,to observe the changes of dynamic electrocardiogram indexes （Heart Rates, Rhythm of the Heart, HRV, SDANN, RMSSD, PNN50, LF, HF, LF/HF, ST-T）. Results Heart rates of DM group increased more significantly than the control group（P〈0. 05）. The index of heart rate variability（HRV） of DM group decreased more obviously than the control group （P〈0.05）. Incidence rates of cardiac arrhythmia and ST-T alteration of DM group were significant higher than the control group. Conclusion For the patients with diabetes mellitus, incidence rates of arrhythmia increase obviously, HRV decreases significantly, and the cardiac vagus damages visibly. It is very effective to predict and diagnose DM complicated with neurologic damage and heart disease by dynamic electrocardiogram.
