在以不同剂量(5 、7.5 、10μg/kg/ min) 多巴酚丁胺( Dob) 连续静注的同时,用二维超声心动图(2 DE) 观察陈旧性心肌梗塞(OMI) 患者室壁运动异常( WMA) 节段的收缩运动变化,以检出存活心肌。结果显示Dob - 2DE 在评价存活心肌方面是一种很在价值的检测方法,以7.5μg/kg/min 为国人的最适宜应用剂量。
Patients with old myocardial infarction (OMI) were observed with two-dimensional echocardiography (2 DE) while continuous intravenous infusion of dobutamine (Dob) at various doses (5, 7.5, 10 μg / kg / min) Changes in contractile motion of the wall motion abnormalities (WMA) segment to detect viable myocardium. The results showed that Dob - 2DE is a very valuable method for the evaluation of viable myocardium. The most suitable application dose of Dob - 2DE is 7.5μg / kg / min for Chinese.
