作者对48例胸痛病例进行活动时心电图监护和踏车负荷试验,并与冠状动脉造影结果作对比。方法:48例冠心病例,年龄36岁～70岁,平均46岁。男性33例,女性15例。48例中27例有典型心绞痛,其余病例的胸前区症状则与劳累无关。静息12导联心电图32例正常,7例为陈旧性心肌梗塞,9例为持续性ST-T变化。患者在2个月内,先后作Holter 24小时活动时心电图监护、亚极量多级踏车运动试验和选择性冠状动脉造影。踏车运动试验的阳性标准为S-T段水平或下垂型压低≥1毫米持续80毫秒,若静息时已有S-T段变化,则S-T段须再压低1毫米。活动时心电图监护的阳性标准为连续15个以上心动的S-T段比
The authors performed electrocardiogram monitoring and treadmill load tests on 48 cases of chest pain and compared them with those of coronary angiography. Methods: 48 cases of coronary heart disease, aged 36 years to 70 years, mean 46 years. 33 males and 15 females. Of the 48 patients, 27 had typical angina and the rest of the chest had no symptoms of fatigue. Resting 12-lead electrocardiogram was normal in 32 cases, 7 cases of old myocardial infarction, and 9 cases of persistent ST-T changes. Patients within 24 months had Holter 24-hour ECG monitoring, submaximal treadmill exercise testing, and selective coronary angiography. The positive standard treadmill exercise test is S-T level or sagging type pressure≥1 mm for 80 ms. If the S-T segment has been changed during rest, the S-T segment should be depressed by 1 mm. When the event of positive ECG monitoring for more than 15 consecutive heart S-T segment ratio
