目的应用定量组织成像技术测量肺叶切除术前、术后右心室局部室壁运动参数，监测右心功能变化。方法应用定量组织速度成像技术测量20例左肺叶切除患者术前2-7天及术后7-15天的右室壁局域心肌长轴运动参数。比较术前、术后的参数变化。结果右心室局部心肌在右室游离壁上的速度参数均有显著变化。结论肺叶切除术后患者右室壁收缩力增强，组织速度成像技术可以作为右室长轴收缩功能监测的手段之一。
目的應用定量組織成像技術測量肺葉切除術前、術後右心室跼部室壁運動參數，鑑測右心功能變化。方法應用定量組織速度成像技術測量20例左肺葉切除患者術前2-7天及術後7-15天的右室壁跼域心肌長軸運動參數。比較術前、術後的參數變化。結果右心室跼部心肌在右室遊離壁上的速度參數均有顯著變化。結論肺葉切除術後患者右室壁收縮力增彊，組織速度成像技術可以作為右室長軸收縮功能鑑測的手段之一。

Objective To assess the effect of pulmonary resection on right ventricular performance by Quantity Tissue Velocity Imaging(QTVI) . Methods Quantity Tissue Doppler Imaging was performed in 20 subjects with pulmonary resection to calculate the preoperative 2-7 days and in postoperative 7-15days. Right Ventricular (RV) myocardium longitudinal systolic function was measured by QTVI. The velocity were separately measured. Results There was a velocity gradient along the RV free wall. There were significant decrease in the peak myocardial velocity in isodiametrical period. Conclusion There were transient hemodynamic changes of right heart in pulmonary resection patients. QTVI may measure Right Ventricular (RV) myocardium longitudinal systolic function.
