摘要
目的:探讨实时三平面超声成像(RTTU)对测量正常人群左心房功能的可行性和临床应用价值。方法:使用实时三平面超声技术,评价32例健康体检的成年人左心房功能(包括左心房存贮容积、管道容积及主动射血分数),同时用二维超声心动图检测上述参数,比较两种方法的相关性和一致性。结果:两种超声检查方法在左心房存贮容积(LARV)、左心房管道容积(LACV)及左心房射血分数(LVEF)等指标方面相比,无差异;LARV、LACV及LAEF在三平面图像和二维超声图像显示具有较好的相关性,差异有统计学意义(rLARV=0.82,rLACV=0.85,rLVEF=0.88;P<0.05)。结论:实时三平面超声成像与二维超声心动图在评价正常人左心房功能时有良好的相关性。
Objective： To evaluat＇e the clinical efficacy of left＇left atrial functi＇onfor the healthy by using real-time three plane ultrasonic imaging in. Methods： The three plane real-time ultrasound imaging was used for evaluation healthy people of left atrial function in 52 adults （including storage volume of left atrium, left atrial pipeline volume, left ventricular ejection fraction）. At the same time, the two-dimensional echocardiography was also used to detect the parameters which were to compare two methods of correlation and consistency. Results：Two methods of ultrasonic examination in LARV, LACV and LVEF indicators have no obvious difference; LARV, LACV and LAEF in three plane image and two-dimensional ultrasound images show good correlation, the correlation coefficient r^LARV=0.82, r^LACV=0.85, r^LVEF=0.88, P〈0.05）. Conclusion： Real-time three plane ultrasound imaging and two-dimensional echocardiography in the assessment of left atrial function of normal people have a good correlation.
