【摘要】 目的　研究多巴酚丁胺 -阿托品负荷超声心动图对冠心病的诊断价值。方法　对 14例正常对照组和 3 5例临床可疑冠心病患者组行多巴酚丁胺负荷超声心动图 (DSE)检查 ,其中 2 6例不能达预估心率且未诱发心肌缺血者加用阿托品。结果　单纯使用多巴酚丁胺达预估心率者正常对照组 6例 ,冠心病组 17例 ,检出缺血者 14例 ;加用阿托品后达预估心率者正常对照组 8例 ,冠心病组 18例 ,检出心肌缺血者 10例。DSE检查中加用阿托品较单纯使用多巴酚丁胺诊断冠心病的敏感性由 40 %升至 68 8%。结论　多巴酚丁胺阿托品负荷试验对冠心病的诊断具有重要的临床实用价值更多还原

【Abstract】 Object To evaluate the effect of dobutamine-atropine stress echocardiography test on detection of myocardial ischemia Method Dobutamine stress echocardiography was performed in 14 normals and 35 patients Atropine was given to 26 cases who couldn’t attain target heart rate(HR) Results HR of 6 Normals attained target,HR of 17 patients attained target ,14 patiened were diagnosed CAD after administration of Dobutamine alone 8 Normals and 18 patients attained target HR and 10 patients were diagnosed myocardial ischemia after additional atropine Sensitivity of DES was 40% with dobutamine alone and 68 6% after the addition of atropine Conclution:Dobutamine-Atropine stress tests have important value for clinical coronary artery disease diagnosis更多还原
