目的:评价动态心电图对冠心病的诊断价值。方法:选择176例冠状动脉造影阳性的患者,回顾分析其动态心电图心肌缺血的变化。结果:176例患者中动态心电图检查心肌缺血阳性率为75.6%,其中3支、双支、单支病变阳性率分别为90.2%、73.7%和68.4%;动态心电图ST段压低幅度、持续时间、出现阵次随冠脉狭窄支数增多、程度增强而显著增加。结论:动态心电图是理想的筛查冠心病的无创伤性检查技术,特别是对双支及以上病变的冠心病患者。
Objective: To evaluate the diagnostic value of ambulatory electrocardiogram in coronary heart disease. Methods: A total of 176 patients with positive coronary angiography were enrolled in this study. The changes of their dynamic electrocardiogram myocardial ischemia were retrospectively analyzed. Results: The positive rate of myocardial ischemia in electrocardiogram was 75.6% in 176 patients. The positive rates of three branches, two branches and one branch were 90.2%, 73.7% and 68.4% respectively. The ST depression range, duration , With the number of coronary stenosis increased, the degree increased significantly increased. Conclusion: Holter is an ideal noninvasive technique for screening coronary heart disease, especially in patients with coronary artery disease of double or more branches.
