摘　　要：目的应用实时三维超声心肌节段运动幅度的牛眼图（IBE）分析扩张型心肌病（DCM）患者左室心肌节段运动的差异性。方法对43例DCM患者的左室代偿运动节段进行了IBE定量分析，根据IBE上色彩的分布计算代偿运动节段百分比（PCS），并计算左室17节段的最大运动幅度（Emax）、最小运动幅度（Emin）、平均运动幅度（EA）、左室节段运动幅度离散度。结果IBE技术观察到DCM组的PCS为27．22％，DCM组的Emax、Emin、EA、左室节段运动幅度离散度与对照组比较差异均有统计学意义（P〈0．001）。DCM患者心肌节段运动的差异有统计学意义，且其左室收缩运动减低在空间分布上无规律性。结论IBE技术获取的PCS、左室节段运动离散度等为DCM患者选择治疗方案、判定预后提供了直观且简便的观察手段。Objective To explore the differences of systolic segmental motion of left ventricle（LV） in patients with dilated cardiomyopathy （DCM） using illustration of the bull eye （IBE） from real time threedimensional echocardiography（RT-3DE）. Methods Quantitative analysis of LV segmental function was made in 43 patients with DCM by IBE. Percentage of compensated segments （PCS） was determined according to the segmental distribution by different color from /BE. Maximal excursion（Emax）, minimal excursion（Emin）, average excursion（EA）, standard difference of excursion（SD） and dispersion of excursion（Edis） were calculated. Results PCS in patients with DCM was 27.22%. Significant differences between DCM group and control group in Emax, Emin, EA,SD and Edis were observed（ P d0. 001 ）. Significant difference in segmental motion of LV was existed in patients with DCM and its distribution of motion seems tendency of irregularity. Conclusions PCS and Edis from IBE might provide a convenient and macroscopic modality in selection of treatment and evaluation of prognosis in patients with DCM.
