【摘要】 为探究实时三维超声心动图(RT-3DE)技术在评估中度、重度肺动脉高压患者右心室收缩功能中的应用,文章选取肺动脉高压患者185例作为研究对象,另选取同时段体检健康者150例作为对照组,分析各组右心室整体容积分数指标、三维超声心动图参数、三尖瓣环位移参数指标。结果发现,中、重度组EDV、ESV、RVEDV、RVESV、RVSV指标水平高于对照组,SV、EF、EDV、RVEF水平低于对照组(P<0.05);中、重度组T1、T2、Tm及Tm%测值高于对照组(P<0.05)。由此可见,使用RT-3DE技术对中、重度肺动脉高压患者进行检测有着较为准确的诊断结果。更多还原

【Abstract】 In order to explore the application of real-time three-dimensional echocardiography(RT-3 DE) technology in the evaluation of right ventricular systolic function in patients with moderate and severe pulmonary hypertension, 185 patients with pulmonary hypertension admitted were prospectively selected as the research object, and another 150 healthy people in the same period were selected as the control group. The parameters of right ventricular global volume fraction, three-dimensional echocardiography and tricuspid annular displacement were compared. The results showed that the levels of EDV, ESV, RVEDV, RVESV and RVSV in moderate and severe group were higher than those in control group, and the levels of SV, EF, EDV and RVEF in moderate and severe group were lower than those in control group(P<0.05). The values of T1, T2, TM and TM% in moderate and severe group were higher than those in control group(P<0.05). It can be seen that the use of RT-3 DE technology in the detection of moderate and severe pulmonary hypertension patients has more accurate diagnostic results.更多还原
