组织多普勒在评价节段性室壁运动异常中的临床价值

目的：探讨组织多普勒（tissue Doppler imaging，TDI）在评价节段性室壁运动异常中的临床价值。方法超声观察50例冠状动脉粥样硬化性心脏病（冠心病）患者（患者组）及50名健康人（对照组），常规超声检查指标包括房室腔大小、左心功能（收缩、舒张功能）测定；超声心动图TDI条件下，于心尖两腔心、三腔心、四腔心切面获得基底段、中段的室间隔、侧壁、后壁、下壁、前壁、前间隔室壁运动达到最大位移时间，通过Q-分析软件（quantification analysis system）计算同一短轴切面不同节段达到最大位移的延迟时间。结果病例组较对照组时间明显延迟。结论 TDI测定同一短轴切面不同节段达到最大位移延迟时间对于评价节段性室壁运动异常具有重要的临床价值。

The clinical value of tissue Doppler imaging in evaluating regional wall motion abnormality

Objective To study the clinical value of tissue Doppler imaging（TDI） on evaluating regional wall motion abnormality. Methods Fifty cases with coronary heart disease （patients group） and 50 cases of healthy people （control group） were collected. By ultrosonic examination the heart chamber size, left heart function （including systolic function and diastolic function） were tested; By TDI, through apical two, three, four chamber, the time of reaching the most displacement of different segment in ventricular septal, side wall, posterior wall, inferior wall, anterior wall and anterior interventricular septal of basal segment and middle segment could be collected. Then through Q-analysis sys-tem the delay time of different segment in the same short axis view could be got. Results Patients group was obvoisly delayed than the control group. Conclusion The delay time of reaching the most displacement of different segment in the same short axis view is very important for assessing the clinical value of the regional wall motion abnormality.
