自七十年代Bonoris氏等报道以来,人们试图采用运动试验(ET)中R波振幅变化的新标准来提高ET心电图对冠心病诊断的敏感性和特异性。本文对42例急性心肌梗塞(AMI)后1～28月的患者进行次极量踏车ET,旨在探讨ET后R波振幅变化对心肌梗塞患者的诊断价值。
Since reports by Bonoris et al. In the seventies, people have tried to adopt the new standard of R wave amplitude change in exercise test (ET) to improve the sensitivity and specificity of ET electrocardiogram in the diagnosis of coronary heart disease. In this paper, 42 patients with acute myocardial infarction (AMI) from January to 28 were treadmill treadmill treadmill exercise treadmill exercise test to investigate the changes of R wave amplitude after ET in patients with myocardial infarction.
