【摘要】 本文对59名患者进行了多普勒超声心动图和X线造影检查,根据心脏手术及X线造影结果来评价多普勒超声心动图探测瓣膜返流的敏感性和特异性。结果表明:多普勒超声心动图可较准确地探测主动脉瓣和二尖瓣返流,其探测主动脉瓣返流的敏感性和特异性分别为93.8％,87.5％;探测二尖瓣返流的敏感性和特异性分别为75％,91.4％。本文也提示:多普勒超声心动图探测瓣膜返流除存在假阳性外,也存在假阴性,并针对其产生原因进行探讨。更多还原

【Abstract】 Fifty nine patients were examined by Doppler echocardiography and cineangiocardiogra-phy to detect aortic regurgitation (AR) and mitral regurgitation (MR). Evaluation of the Doppler echocardiogrgahic sensitivity and specificity for diagnosis of AR and MR was based on the results of cineangiocardiographic and operation findings. The figures obtained as follows 93.8% and 87.5% for AR; 75% and 91.4% for M.R. respectively: The Doppler echocardiography may yield both false positive and false negative results. The causes or factors that may influence the diagnostic accuracy were discussed.更多还原
