Richards 指出,两维超声心动图(2DE)检出冠心病的标准有三项:(1)静息时室壁运动异常;(2)运动中新出现的室壁运动异常;(3)运动中左室喷血分数未能增加。以前研究大多以静息时室壁运动异常者为对象,即以冠心病先验概率甚高者为对象,故2DE 运动试验检出冠心病的敏感性过高。Ryan 等以静息时室壁运动正常者为对象,以运动后即刻出现一过性室壁运动异常为阳 Richards pointed out that two-dimensional echocardiography (2DE) to detect coronary heart disease has three criteria: (1) resting resting wall motion; (2) exercise in the new wall motion abnormalities; (3) left Room spurt score failed to increase. Previous studies mostly resting ventricular wall motion abnormalities as the object, that is, a high probability of coronary heart disease prior to the object, so 2DE exercise test detected coronary heart disease is too high sensitivity. Ryan, etc. to rest at normal ventricular wall motion as the object, immediately after exercise appeared abnormal ventricular wall motion abnormal Yang
