心电图ST-T改变与冠状动脉造影结果对比分析

目的：探讨通过与冠状动脉造影(CAG)结果相比，冠心病患者心电图(ECG)ST-T改变的相关血管病变的诊断价值。方法：选择120例均以Judkins技术经股动脉行冠状动脉造影且结果阳性的冠心病患者。对比分析其心电图ST-T改变所对应的血管病变。结果：120例患者ECG定位为前壁、下壁、侧壁、广泛心肌缺血者分别为58、16、20、26例。前壁心肌缺血预测左前降支(LAD)病变的诊断符合率为86.2％；下壁心肌缺血预测右冠状动脉(RCA)病变的诊断符合率为62.5％；侧壁心肌缺血预测左回旋支(LCX)病变的诊断符合率为55.0％；广泛心肌缺血判定左主干(LMCA)病变的诊断符合率为61.5％。结论：心肌缺血ECG定位可以用以初步判断冠心病缺血相关动脉。

Analysis of the relationship between change of electrocardiogram ST - T and coronary result of coronary angiography

Objective: To investigate the predictive value of ECG in coronary heart disease patients, Passing to coronary angiography ( CAG) result. Method: Coronary angiography of 120 patients was performed via femoral artery to define the culprit vessel using the Judkins technique and was masculine gender.The relationship between changes of ECG and angiograms has contrasted. Result: Anterior,inferior, lateral and extensive myocardial ischemia in 58,16,20 and 26 cases respectively according to the orientation of ECG of 120 patients .The tally rate between anterior myocardial ischemia and focus of left anterior descending coronary artery (LAD)was 86.2%; The tally rate between inferior myocardial ischemia and focus of right coronary artery ( RCA) was 62.5%; The tally rate between lateral myocardial ischemia and focus of left circumflex coronary artery (LCX) was 55.0%; The tally rate between extensive depression of segment and focus of left main coronary artery ( LMCA)was 61.5%. Conclusion: It was feasible to define ischemia-related artery with alteration of ST segment or T wave orientation in ECG.
