摘要
目的分析糖尿病患者心率变异性与心室复极离散度相关性。方法所有患者分为3组:组1,单纯糖尿病组48例;组2,糖尿病合并冠心病组50例;组3,正常对照组,50例。对各组患者均进行心电图及动态心电图检查,记录心率变异性及测量Tp-Te值,分析心率变异性与心室复极离散度相关性。结果组1、2心率变异性较正常对照组降低。组1心室复极离散度较正常组增大,但差异无统计学意义。组2心室复极离散度较正常对照组明显增大。结论冠心病合并糖尿病患者心率变异性降低,心室复极离散度增大,单纯糖尿病患者多无心肌缺血表现,其心率变异性降低但是心室复极离散度并未增大。在心肌缺血的情况下心率变异性与心室复极离散度有一定的相关性,但其机制确有待进一步研究。
Objective To analyze the correlation of heart rate variability and dispersion of ventricular repolarzation in diabetes patients. Methods All the patients were divided into three groups, 48 patients with pure diabetes in group 1; 50 patients with diabetes combined with coronary artery disease in group 2, 50 patients without diabetics and coronary artery disease in group 3 as control group. All patients accept electrocardiogram exam and 24 hours' dynamic ECG. The index of heart rate variability and TP-TE value were analyzed. Results Heart rate variability in group 1 and 2 was lower than group 3. Dispersion of ventricular repoiarzation between group 1 and 3 had no difference. Dispersion of ventricular repolarzation in group 2 was much lower than group 3. Conclusion The patinets with diabetes mellitus combined with coronary heart disease have lower heart rate Variability, and higher dispersion of ventricular repolarzation; pure diabetic patients have lower heart rate variability, but the dispersion of ventricular repolarzation is not different. When patients with diabetes mellitus onseting myocardial ischemia, their heart rate variability and dispersion of ventricular repolarzation have a certain correlation. Now the mechanism is steel unknown.
