动态心电图变化与冠状动脉病变相关性分析(英文)

目的:探讨动态心电图诊断冠状动脉病变的价值。方法:选择我院有"心绞痛"史住院患者100例,行24h动态心电图检查,并与冠状动脉造影结果进行对比分析。结果:100例患者中,动态心电图阳性85例患者中,冠脉造影阳性70例,冠脉造影阴性15例;15例动态心电图正常者,其中冠脉造影阴性10例,冠脉造影阳性5例,以冠脉造影为金标准,动态心电图诊断冠心病的敏感性为93.3%特异性为40.0%,阳性预测值(准确性)为82.4%,阴性预测值为66.7%。部分病人有"心绞痛",冠脉造影无狭窄,但有慢血流。结论:动态心电图是诊断冠心病的重要检查方法之一,它简单、实用、安全、经济,适合临床广泛应用,但特异性仅40.0%,阴性者不能排除冠心病。

Relationship between change of dynamic electrocardiogram and coronary artery disease

Objective：To explore diagnostic value of dynamic electrocardiogram（DCG） on coronary artery disease.Methods：A total of 100 inpatients with ＂ angina pectoris ＂ history from our hospital were enrolled and received 24h DCG measurement.The DCG examination results were compared with those of coronary angiography（CAG） and analyzed then.Results：Among the 100 patients,there were 85 patients with positive DCG,including 70 cases with positive CAG and 15 cases with negative CAG;and 15 patients with normal（negative） DCG,including 10 cases with negative CAG and five cases with positive CAG.With CAG as golden standard,sensitivity,specificity,positive predictive value（accuracy） and negative predictive value of DCG in diagnosis of coronary heart disease were 93.3%,40.0%,82.4% and 66.7% respectively.Partial patients had ＂ angina pectoris ＂,no stenosis in CAG but there′s slow blood flow.Conclusion：Dynamic electrocardiography is one of important measuring methods diagnosing coronary heart disease.It is simple,practical,safe,economic and appropriate for wide application in clinic,but its specificity is just 40.0%,so coronary heart disease cannot be excluded in negative patients.
