体表心电图与冠状动脉造影在急性冠状动脉综合征中的对比分析

Analysis on ECG and coronary artery disease in patients with acute coronary syndrome

目的探讨心电图(ECG)改变与冠状动脉病变的关系。方法对83例临床诊断为急性冠状动脉综合征(ACS)的病人ECG与选择性冠状动脉造影(CAG)结果进行对比分析。结果83例ACS冠状动脉病变ECG检出阳性率为67.6%;非ST段抬高的ACS以多支中、重度血管病变为主。ST段抬高的前壁心肌梗死以前降支病变为主,下壁心肌梗死以右冠状动脉病变为主。结论ECG对ACS诊断价值较大,但单纯通过ST-T异常诊断冠心病易导致误诊、漏诊。

Objective To explore the changes in ECG and coronary artery disease and analyze the results of the acute coronary syndrome （ACS） in patients with electrocardiogram （ECG） and selective coronary angiography （CAG）. Methods 83 cases of clinically diagnosed as ACS patients with ECG results of CAG were analyzed. Results Comparing with CAG, positive rate of ECG detection was 67.6% in 83 cases of ACS coronary artery disease for non - ST - segment elevation ACS to more than moderate, severe vascular disease - oriented. Conclusions ECG diagnosis of ACS larger value, but simply through the ST - T abnormalities led to the diagnosis of coronary heart disease misdiagnosed easily missed.
