Abstract：Objective To explore the diagnostic value of dynamic electrocardiogram (DCG) in evaluating myocardial ischemia. Methods 243 inpatients who were diagnosed coronary heart disease by dynamic electrocardiogram and coronary angiography were enrolled as the coronary heart disease group. Meanwhile,123 case of normal persons who were matching with the 120 inpatients in genders and ages were enrolled as the control group and their ECG data were also analyzed. Results There were ECG changes in 83 cases (67.48%) of the coronary heart disease group and in 34 cases (28.33%)of the control group,with statistically significant differences. The ECG changes mainly concentrated on ST segments and total ischemic burden larger.In the aspect of heart rate,the coronary heart disease group was significantly faster than the control group,with (79.72 ± 12.98) times/min in the former and (71.29 ± 10.14) times / min in the latter,and the differences were statistically significant.Many vascular lesions group the total ischemia burden was significantly larger than the single vascular lesions group ,and the differences were statistically significant. Conclusion Dynamic electrocardiogram on the diagnosis and prognosis of coronary heart disease has an important reference value.
