目的研究探讨动态心电图对冠心病的临床诊断价值.方法选择2010年3月-2012年4月我办收治的冠心病患者45例为研究对象,所有患者均进行12导联动态心电图检查和冠状动脉造影检查,分析12导联动态心电图的诊断准确率.对比不同病变冠心病患者的12导联心电图诊断价值.结果冠状动脉狭窄在50%以上患者35例,其中使用12导联动态心电图检查,检出缺血性 ST 段改变30例.其中多支病变组患者诊断准确率高于单支病变组,p <0.05.结论使用动态心电图检查对冠心病的诊断价值较高,尤其是对多支病变组诊断更准确.“,”Objective: To study the dynamic electrocardiogram of coronary heart disease in clinical diagnostic value. METHODS: March 2010 to April 2012, 45 cases in our hospital in patients with coronary heart disease for the study, al patients underwent 12-lead Holter checks and coronary angiography, analysis of 12-lead Holter diagnostic accuracy rate. Contrast the different lesions in patients with coronary heart disease, 12-lead ECG diagnostic value.Results: Coronary artery stenosis more than 50% in 35 patients, including the use of 12-lead Holter detection of ischemic ST-segment changes of 30 cases. Multivessel disease patients diagnostic accuracy rate in single-vessel disease (p <0.05). Conclusion: The use of dynamic ECG for diagnosing coronary artery disease, in particular, a more accurate diagnosis of multivessel disease.
