一过性 ST 段改变是最广泛应用的非侵入性的急性心肌缺血的指征。本文通过运动负荷试验和动态心电图监测来研究一过性心肌缺血期间的 S 波振幅改变。研究组为慢性稳定型劳力性心绞痛病人50例,平均年龄60±8(43～69)岁,男40例,女10例。对照组为无心脏病男性志愿者10名,年龄平均24±2(22～29)岁。两组病例均行平板运动试验。心绞痛组10例,对照组4名行24小时动态心电图检查,21例行潘
A transient ST-segment change is the most widely used indication of non-invasive acute myocardial ischemia. In this paper, exercise-load test and Holter monitoring to study the transient amplitude of S-wave amplitude during myocardial ischemia. The study group consisted of 50 patients with chronic stable angina pectoris who had an average age of 60 ± 8 (43-69) years, 40 males and 10 females. The control group was 10 male volunteers without heart disease, with an average age of 24 ± 2 (22-29) years. Two groups of patients underwent treadmill exercise test. 10 cases of angina pectoris group, 4 cases of control group, 24-hour Holter examination, 21 cases of pan
