超声心动图、放射性核素心血管造影及~(201)Tl心肌显像在标准运动试验中的应用大大提高了冠心病(CAD)诊断的准确性。其中运动二维超声心动图(E2DE)更较理想。节段性室壁运动异常(SWMA)的检出可能是急性缺血和梗塞的最早征象,往往早于心电图及Q波的产生及血清酶学改变。尤适用于静息超声心动图正常的CAD患者。
Echocardiography, radionuclide angiography and ~ (201) Tl myocardial imaging in standard exercise tests greatly improve the accuracy of the diagnosis of coronary heart disease (CAD). Two-dimensional exercise echocardiography (E2DE) is more ideal. The detection of segmental wall motion abnormalities (SWMA) may be the earliest signs of acute ischemia and infarction, often earlier than electrocardiogram and Q waves and changes in serum enzymes. Especially suitable for resting echocardiography normal CAD patients.
