我们应用二维多普勒超声心动图对35例慢性肾衰患者的心脏瓣膜返流进行观察,其中男性22例,女性13例,年龄20～74(平均47)岁,并设正常对照组40例。仪器使用日本东芝SSH—60A二维多普勒超声诊断仪,探头频率2.5MH_2,取平卧或左侧卧位于胸骨左缘心脏各切面检测心内结构,运用脉冲和连续多普勒超声技术检测各瓣口的血流频谱,测定瓣膜返流有关的多项血流频谱参数,用半定量方法估测瓣膜返流的程度。结果:正常组与肾衰组的二尖瓣和主动脉瓣返流
We used two-dimensional Doppler echocardiography in 35 cases of chronic renal failure in patients with heart valve regurgitation were observed, including 22 males and 13 females, aged 20 to 74 (mean 47) years, and the control group 40 example. Instrument using Japan’s Toshiba SSH-60A two-dimensional Doppler ultrasound diagnostic apparatus, the probe frequency 2.5MH_2, supine or left lying in the left heart of the sternal heart section detection of intracardiac structure, the use of pulse and continuous Doppler ultrasound detection The blood flow spectrum of each valve orifice was used to measure the spectral parameters of multiple blood flow related to valve regurgitation. The degree of valvular regurgitation was estimated by semi-quantitative method. Results: The mitral regurgitation and aortic valve regurgitation in normal group and renal failure group
