Objective To study the value of dynamic twelve lead electrocardiogram for the diagnosis of occult coronary artery disease. Methods Dynamic twelve lead ECG was done to 12 cases, who had risk factors of coronary heart disease. And, the person with positive result was done with coronary photo lithography to control coronary angiography and determine the dynamic twelve lead electrocardiogram diagnosis of occult coronary artery disease accuracy and lesion severity and its predictive value. Results In the twelve-lead Holter positive population, 71％ of the patients were diagnosed with coronary heart disease. And compared to the ischemic group, in the severe degree of ischemia group, the number of patient with coronary artery stenosis( ≥ 75％) was statisti cally increased. There was a good correlation between holter positioning of the ischemic area and coronary artery stenosis. Conclusion Twelve leads Holter of occult coronary artery disease have a better screening value%目的 研究十二导联动态心电图对隐匿性冠心病诊断的初筛价值.方法 对有冠心病危险因素者行十二导联动态心电图检查,对其中阳性结果者行冠状动脉造影术,对照冠状动脉造影结果,判定十二导联动态心电图对隐匿性冠心病诊断的准确性以及对其严重程度和病变部位的预测价值.结果 在十二导联动态心电图阳性人群中,71%的患者被确诊为冠心病,缺血程度严重组与缺血程度较轻组比较,冠脉狭窄大于或等于75%者明显增多,二者相比差异有统计学意义,十二导联动态心电图定位的缺血部位与冠状动脉血管狭窄部位有较好的相关性.结论 十二导联动态心电图对隐匿性冠心病有较好的初筛价值.
