12导联动态心电图与冠状动脉造影结果的对比分析
摘要
Objective: To discuss the value of the 12-lead dynamic electrocardiogram (DCG) in diagnosis of coronary heart disease(CHD) by comparing and analyzing the results between 12-lead DCG and coronary angiography. Methods : 105 patients with suspected CHD undergoing both 12-lead DCG and coronary angiography were analyzed. Results : 105 patients with positive coronary angiography of 46 cases, 59 cases were negative, of which 12 lead DCG showed ischemic ST segment depression in 32 patients, no ST-segment depression in 14 cases, normal coronary angiography in 59 cases of 12-lead DCG showed ischemic ST segment depression in 23 patients, no ST-segment depression in 36 cases. Conclusion : 12-lead DCG is one of ideal non-invasive methods in the diagnosis of CHD of ischemic ST segment depression with typical chest pain.It is simple,economic and practical.
