本文分析目的是根据冠脉造影对比动态心电图ST-T改变估价其对冠心病的诊断价值。在36例冠脉造影病例中,23例临床诊断为冠心病,其造影阳性结果为16例(69.6％),其它高血压、病态窦房结综合征等13例的造影均阴性。本组23例冠心病患者9例(39.1％)有动态心电图ST-T改变,其表现为ST段水平型压低0.15—0.2mV或T波对称性减低≥0.2mV。其冠状动脉造影均显示为中-重度狭窄,而呈轻度狭窄者未见动态心电图改变。1例高血压患者的ST段水平型压低0.3mV,但冠状动脉造影阴性。因此动态心电图的ST-T改变是非特异
The purpose of this analysis is to assess the diagnostic value of ST-T in patients with coronary heart disease based on coronary angiography contrast dynamic ST-T changes. Among 36 cases of coronary angiography, 23 cases were clinically diagnosed as coronary heart disease. The positive results of angiography were 16 cases (69.6%). Other hypertension, sick sinus syndrome and other 13 cases were negative. The group of 23 patients with coronary heart disease in 9 cases (39.1%) have dynamic ECG ST-T changes, which showed ST-level depression 0.15-0.2mV or T-wave symmetry decreased ≥ 0.2mV. The coronary angiography showed moderate-severe stenosis, and showed mild stenosis who did not change the dynamic ECG. One case of hypertensive patients with ST-segment horizontal pressure down 0.3mV, but negative coronary angiography. Therefore, the dynamic electrocardiogram ST-T changes are non-specific
