多普勒组织成像在甲亢患者室壁运动检查中的价值

Value of Doppler Tissue Imaging in the Examination of Ventricular Wall Motion of Patients with Thyroidism

目的 探讨甲亢患者心脏的组织多普勒表现。方法 应用多普勒组织成像 (Dopplertissueimaging ,DTI)速度模式的方法 ,观察甲亢患者和正常人室壁运动的区别。结果 甲亢组室壁运动色彩较正常组明亮 ,频谱多普勒曲线上 ,甲亢组在收缩期、舒张期室壁运动各峰值均大于正常组 ,两组有显著差别 (P <0 .0 1)。结论 甲亢患者心肌运动功能增强 ,说明DTI是一种新的较敏感的检测心肌室壁运动功能的方法。

Objective To discuss the value of Doppler tissue imaging in the examination of venticular wall motion of patients with thyroidism.Method Doppler tissue imaging(DTI) was used to detect the velocity of left ventricular wall motion in 20 people(normal group) and 35 cases of thyroidism.Results Ventricular wall motion colour in thyroidism group was brighter than that in the normal group.On Doppler wave,every speed of wave peak in both systole and diastole in thyroidism group was faster than that in the normal group.These differences were significant.Conclusions The study indicates that DTI is a new senitive method for assessment of venteicular wall motion and myocardial function.
