【摘要】 目的 通过定量组织速度成像技术(QTVI)结合多巴酚丁胺负荷超声心动图(DSE)诱导的室壁运动异常与冠状动脉造影结果相对照，分析室壁运动异常与冠脉血供的关系。方法 对68例临床疑诊为冠心病的患者进行定量组织速度成像技术—多巴酚丁胺负荷超声心动图及冠状动脉造影(CAG)检查，判定室壁运动异常的部位、范围及病变血管。结果 本组68例患者中以冠状动脉造影为标准，定量组织速度成像技术—多巴酚丁胺负荷超声心动图诊断冠心病的敏感性85.7%,特异性89.4%,准确性86.7%。结论 应用定量组织速度成像技术—多巴酚丁胺负荷超声心动图能较准确的评价室壁运动异常及对应血供关系，是诊断冠心病的一种安全、简单、经济的有效方法。

    【Abstract】 Objective We combined the results of regional wall motion abnormality(RWMA) from quantitative tissue velocity imaging (QTVI)and dobutamine stress echocardiography(DSE) in order to evaluate the correlation between regional wall motion abnormality and the number of impaired coronary arterigs.Methods We examined 68 patients with suspected coronary artery disease using QTVI and DSE and combined with coronary angiography for analyzing the association of abnormal regional wall motion and the severity of coronary artery stenosis.Results The sensitivity ......
