冠脉病变的精确识别常受到心电图运动试验敏感性和特异性差的限制.晚近报告了应用与运动时峰值心率相关的 ST 段压低变化的直线回归分析的运动心电图评价来精确地区分无、有1支、2支和3支冠脉病变的病人.本文通过研究50例疑有冠脉缺血病人的运动心电图和冠状动脉电影造影来估价上述这种方法的实用价值.
The precise identification of coronary lesions is often limited by the sensitivity and specificity of the ECG exercise test.Recent reports report the use of a linear regression analysis of electrocardiographic assessment of linear regression of ST-segment depression associated with peak heart rate during exercise to accurately distinguish between none Branch, 2 and 3 coronary artery disease patients.In this paper, 50 cases of suspected coronary artery disease patients with exercise ECG and coronary angiography to assess the value of this method.
