摘　　要：目的比较三维斑点追踪成像(3DSTI)、M型和二维超声心动图(2DE)检测扩张型心肌病(扩心病)患者左心室射血分数的结果。方法 31例扩心病患者,分别连续运用3DSTI、M型和2DE检测左室收缩末期容积(LVESV)、舒张末期容积(LVEDV)及射血分数(LVEF),分析比较三种方法所得结果之间的异同。结果三种方法所测得LVESV、LVEDV和LVEF皆呈显著正相关,均数比较差异皆无统计学意义。结论在扩心病患者,三种方法所测得LVEF值皆准确、可靠。Objective The three measurements for left ventricular ejection fraction by 3 dimensional speckle tracking imaging（3 DSTI）、M-mode and two-dimensional echocardiography（2 DE）were comparatively studied in Patients with dilated cardiomyopathy（DCM）.Methods End-diastolic volume（LVEDV）,end-systolic volume（LVESV）and ejection fraction（LVEF）of left ventricle in 31 patients with DCM were measured using the 3 procedures of echocardiography consecutively,and their results were compared and analyzed.Results The LVEDV,LVESV and LVEF were obviously positive correlation and the differences of them were not significant among 3 DSTI,M-mode and 2 DE in the patients with DCM.Conclusions The 3 methods had compatible accuracy and reproducibility in measuring LVEF in patients of DMC.
