一般认为运动后 S-T 段压低的程度和发生率与显著病变的冠状动脉数呈直接关系。心电图负荷试验假阴性常用运动负荷不足或冠状动脉的血液动力学损害不显著和较小来解释,其他可能的解释原因是:(1)未应用12导联心电图,因缺血性 S-T 段改变可
It is generally believed that the extent and incidence of S-T depression after exercise is directly related to the number of coronary arteries in significant lesions. ECG load test false negative common exercise load or coronary artery hemodynamic damage is not significant and small to explain the other possible explanations are: (1) did not use the 12-lead ECG, due to changes in ischemic S-T segment can be
