我们自1990年11月—1994年1月用西德产506D心电图机对急性心肌梗塞(AMI)患者行踏车试验,选出75例资料完整的病例加以分析.对象和方法 75例中男性66例,女性9例,年龄32—67(56.3±11.4)岁.根据典型心绞痛史、心电图(ECG)异常、心肌酶升高等确诊.74例为Q波型梗塞,1例为心内膜下梗塞,剔除合并影响Q-T间期者.其中27例行尿激酶溶栓.发病后22—32(平均27.2)天做踏车试验,先作卧、坐位常规12导联心电图,用1或Ⅱ、aVF、V_5做运动中监护导联.运动6min后记录即刻、2、4、6min监护导联ECG,算出Q-
We performed treadmill tests on patients with acute myocardial infarction (AMI) using a West German-made 506D electrocardiograph from November 1990 to January 1994. We selected 75 cases with complete data to analyze. Subjects and Methods 75 men 66 Cases, female 9 cases, aged 32-67 (56.3 ± 11.4) years old.According to the history of typical angina, electrocardiogram (ECG) abnormalities, elevated myocardial enzymes diagnosed.74 cases of Q wave infarction, 1 case of subendocardial infarction , Excluding the combined effect of QT interval were 27 cases of urokinase thrombolysis.After onset of 22-32 (average 27.2) days treadmill test, first lie, sit routine 12-lead ECG, with 1 or Ⅱ, aVF , V_5 to do exercise monitoring lead.Motion recorded immediately after 6min, 2, 4, 6min guard ECG, calculated Q-
