摘　　要：与２０１铊心肌ＳＰＥＣＴ显像对照检测３５例冠心病患者，评估小剂量多巴酚丁胺超声心动图（ＬＤ－ＤＥＴ）检测缺血后存活心肌的价值。ＬＤ－ＤＥＴ采用两级试验，脱机计算机分析左室室壁运动、左室收缩末期及舒张末期容积及左室射血分数。研究结果：①多巴酚丁胺输入前后，心率、血压、左室容积、射血分数均无显著改变。②检测缺血后存活心肌的敏感度、特异度、阴阳性预告值及总符合率分别为７３％、７２％、７６％、７４％及７２％，对左前降支供血区域的评估能力强，而对左旋支和右冠脉支供血区域评定存在较大差异。Comparison with thallium201 single photon emission computed tomography, lowdose Dobutamine echocardiography were performed in 35 ischemic heart disease patients to assesse it's value in detecting of the viable myocardium. During Dobutamine infusion the heart rate, blood pressure, left ventricular volume and ejection fraction didn't changed. The sensitivity, specificity, positive and negitive predetective value and crude agreement were 73%,72%,76%,74% and 72% respectively. Lowdose Dobutamine echocardiography was more efficient to detect the viable myocardium in segements, which perfused by left anterior descending coronary artery than the segments, which perfused by left circumflex and right coronary artery.
