摘要
目的分析老年糖尿病合并冠心病患者的动态心电图表现,探讨心率变异性的临床意义。方法选取2型糖尿病组患者40例和糖尿病合并冠心病患者58例作为病例组,选择健康者60例作为对照组分别行动态心电图检查,分析其心律失常、心肌缺血的发生率与心率变异性的相关性。结果老年糖尿病合并冠心病组的心律失常、心肌缺血发生率明显高于糖尿病组和正常对照组,糖尿病合并冠心病组的心率变异性指标明显低于糖尿病组和正常对照组,差异有统计学意义(P<0.05)。结论老年糖尿病合并冠心病患者更易引起心脏自主神经功能紊乱、心肌缺血,并发症的存在可能是诱发心律失常的常见原因。
Objective To investigate the clinical significance of heart rate variability( HRV) by analyzing the ambulatory electrocardiographic manifestations of gerontal patients with diabetes and coronary heart disease( CHD). Methods Forty patients with type-2 diabetes and 58 CHD patients complicating diabetes were enrolled in our study as diabetes group and diabetes complicating CHD group,respectively. Sixty healthy people were selected as the control group. Holter examination was performed on the three groups. The relationship between the incidence rate of arrhythmia( myocardial ischemia) and HRV was analyzed. Results Among the CHD patients with senile diabetes,the incidence rates of arrhythmia and myocardial ischemia were both significantly higher than those in the diabetes group and normal control group while the HRV indexes were significantly lower with statistically significant differences( P < 0. 05). Conclusion Senile diabetes and CHD can easily lead to cardiac autonomic nerve dysfunction and myocardial ischemia. The existence of complications is possibly one of the common inducing factors of arrhythmias.
