The AA. studied 96 subjects: 74 normals, 15 patients with pulmonary stenosis, 6 with pulmonary regurgitation and 1 with combined stenosis and pulmonary regurgitation, by using pulsed Doppler echocardiography. This technique, which supplements M-mode echocardiography with Doppler flow detection, allowed determination of direction and quality--laminar or turbolent--of flow through pulmonary valve. In our experience, pulsed Doppler echocardiography is a sensitive and specific method for detection of pulmonary stenosis and regurgitation and extends ultrasound diagnosis beyond the capabilities of M-mode echocardiography.
研究人员使用脉冲多普勒超声心动图对96名受试者进行了研究：74名正常人、15名肺动脉狭窄患者、6名肺动脉反流患者以及1名合并狭窄和肺动脉反流患者。这项技术通过多普勒血流检测对M型超声心动图进行补充，能够确定通过肺动脉瓣的血流方向和性质——层流或湍流。根据我们的经验，脉冲多普勒超声心动图是检测肺动脉狭窄和反流的一种敏感且特异的方法，扩展了超声诊断的范围，超出了M型超声心动图的能力。
