作者的既往研究证实,ST段/心率斜率≥6.0μV/beat/min能准确地确定稳定型心绞痛者3支冠状动脉病变或功能严重受损的2支冠状动脉病变.然而,尽管有严重冠状动脉病变,在急性心肌梗塞后出院前运动试验期间ST段心率斜率偶尔可在正常范围.为进一步估价ST段/心率斜率对检出冠状动脉病变的敏感性和确定3支血管病变的准确性,特此对近期心肌梗塞和稳定型心绞痛者伴或不伴有Q波梗塞的运动心电图和血管造影进行了比较.方法:研究组包括113名有运动心电图及血管造影的冠心病人.58例为稳定型心绞痛,包括17例
Previous studies by the authors confirm that ST-segment / heart rate slope ≥6.0 μV / beat / min can accurately determine 3 coronary artery lesions or 2 coronary lesions with severely impaired function in patients with stable angina.However, despite the presence of severe coronary arteries Lesions, ST-segment heart rate slope may occasionally be in the normal range during pre-discharge exercise test after acute myocardial infarction In order to further assess the sensitivity of the ST segment / heart rate slope to the detection of coronary lesions and to determine the accuracy of the 3-vessel disease, The recent ECG and angiogram of myocardial infarction and stable angina with or without Q wave infarction were compared.Methods: The study group consisted of 113 coronary heart disease patients with exercise ECG and angiography, and 58 patients were stable Angina, including 17 cases
