    [摘要] 目的：探讨实时三维超声心动图(RT-3DE)评价急性肺栓塞(APE)患者右心功能的价值。方法：使用RT-3DE采集30例APE患者和30例健康志愿者心脏全容积图像导入TomTec工作站，应用4D RV-Function软件分析，生成右室容积-时间变化曲线(RV-VTC)。比较两组对象RT-3DE参数右室舒张末期容积(EDV)、收缩末期容积(ESV)，射血分数(EF)，峰值排空率(PER)和峰值充盈率(PFR)之间的差异。结果：与对照组相比，APE患者右室整体EDV、 ESV增大，EF、PER、PFR减小，差异均有统计学意义(t=2.490、2.172、2.897、2.894及3.042，均P<0.05)。结论：APE患者的右室整体收缩及舒张功能减低，RT-3DE可以准确评价APE患者右心功能改变。

    [Abstract] Objective: To explore the value of the right ventricular (RV) global function in patients with acute pulmonary embolism (APE) by using real-time Three-dimensional echocardiography (RT-3DE). Methods: 30 normal controls and 30 patients with APE were studied. And all the three-dimensional echocardiographic datasets were acquired. Then series of RV parameters, namely end diastolic volume (EDV), end systolic volume (ESV), RV ejection fraction (EF) were offline measured by TomTec 4D RV-Analysis software which can also provide the right ventricular volume-time curves (RV-VTC). EDV, ESV, EF, RV peak filling rate (PFR) and RV peak ejection rate (PER) from RT-3DE were investigated in the two groups. Results: Compared with control group, the value of EDV and ESV were larger; EF, PER, PFR were reduced, there were significant differences in the two groups (t=2.490, 2.172, 2.897, 2.894 and 3.042, respectively, all P<0.05). Conclusion: The RV function in patients with APE is decreased and RT-3DE can evaluate RV volume and global function accurately. ......
