摘　　要：目的应用超声二维斑点追踪技术评价肥厚型心肌病患者左心室短轴心尖水平、二尖瓣水平旋转运动及左心室整体扭转运动的特点。方法选取肥厚型心肌病患者30例和正常对照人群30例,应用斑点追踪成像技术分析肥厚型心肌病患者的左心室短轴心尖水平、二尖瓣水平旋转角度和左心室整体扭转角度。结果与正常组比较,肥厚型心肌病患者左心室短轴心尖水平、二尖瓣水平旋转角度和左心室整体扭转角度均显著增加(P>0.05)。结论肥厚型心肌病患者左心室扭转运动较正常人已发生变化,二维斑点追踪技术可以定量评价肥厚型心肌病患者左心室的扭转运动。Objective Characteristics of left ventricular twist in patients with hypertrophic cardiomyopathy （HCM） were assessed by 2D speckle tracking imaging （2D- STI）. Methods HCM group （ n = 30） and normal group （ n = 30） were selected. Left ventricular torsion angles as a whole, rotational angle of the mitral valve and apex were analyzed by 2D- STI. Results Com- pared with the control group, left ventricular two - dimensional strain and torsion angles as Left ventricular, rotational angle of the mitral valve and apex in HCM patients decreased significantly （P 〈 0.05）. Conclusion The left ventricular systolic torsion has already changed in patients with HCM, left ventricular torsion in patients with HCM can be quantitatively evaluated by 2D - STI.
