心电描记术与冠状动脉造影诊断冠状动脉疾病的比较

目的 研究初诊为冠状动脉性心脏病(CHD)患者的心电图特征，决定是否行冠状动脉造影(CAG)的重要性。方法 对临床初诊为CHD患者的心电图和CAG结果进行回顾性分析。结果 在表现有CHD临床症状的66名患者中，心电图检查无心梗及ST—T特征性改变者12人，冠状动脉造影后无冠状动脉狭窄病变者12人，符合率为100％，心电图检查有心梗及ST—T改变者54人，冠状动脉造影后确定为冠状动脉狭窄病变者41人，符合率为76％。结论 对心电图表现无特征性改变、具有CHD临床症状的患者，行CAG检查可有效排除CHD；对心电图表现有特征性改变的CHD患者，及早行CAG检查。可为CHD患者尽早做出正确诊断，明确冠状动脉病变部位。为及早行介入疗法提供可靠依据。

Comparison of electrocardiography and coronary arteriography in the diagnosis of coronary heart disease

Objective To study the Electrocardiogram (ECG) features of patients who were initially diagnosed coronary heart disease (CHD) to make decision for performing the coronary arteriography (CAG). Methods Retroactive analysis on the features of the ECG and CAG of patients who were initially diagnosed CHD was made. Results Of 66 patients, there were 12 whose ECG were no myocardial infarction and ST-T change, and whose coronary arteries were found no stricture by CAG, so both had the same result. Among 54 patients whose ECG were found myocardial infarction and ST-T change , and 41 stricture by CAG. According rate was 76 %. Conclusion To the patients with CHD and without special ECG findings, CAG can early make a clear diagnosis and find the involved site,thus, the evidences are provided to perform the intervenient treatment earlier.
