尽管无症状心肌缺血的报道很多,但运动时心肌缺血同胸痛、ST段改变之间的相互关系却没有资料。~(201)铊显像反映心肌灌注,而不是缺血。负荷超声心动图与心肌灌注显象相比,主要研究运动引起的缺血性功能障碍。仰卧位负荷超声心动图评估冠状动脉疾病高度准确,可以达到两个目的:(1)确定运动引起的缺血量和胸痛、ST段压低
Although there are many reports of asymptomatic myocardial ischemia, there is no data on the relationship between exercise-induced myocardial ischemia and chest pain and ST-segment changes. ~ (201) Thallium imaging reflects myocardial perfusion, rather than ischemia. Compared with myocardial perfusion imaging, stress echocardiography mainly focuses on exercise-induced ischemic dysfunction. Supine position assessment of echocardiographic coronary artery disease with high accuracy can achieve two purposes: (1) to determine the amount of motor-induced ischemia and chest pain, ST depression
