Abstract：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 type2 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.
