摘要
目的 探讨多普勒超声右室流出道血流参数对评价肺心病右室收缩功能的价值。方法 在 2 2例肺心病患者中 ,利用脉冲多普勒超声记录右室流出道 (RVOT)血流频谱参数 ,与放射性核素心室造影测算的右室射血分数(RVEF)对比分析。结果 在RVOT血流参数中右室收缩时间间期 (STI) ,射血期流速积分 (VTI)和平均血流速度 (Vm)与核素造影所测RVEF仅有轻度相关 ,其余测值无相关。结论 肺心病患者的RVOT血流参数难以反映右室收缩功能情况。
Objective To investigate the right ventricular systolic function by Doppler-derived right ventricular outflow tract(RVOT)flow indices in pulmonary heart disease.Methods In 22 patients with pulmonary heart disease,comparative analysis was undertaken between right ventricular outflow tract blood flow parameters obtained by pulsed Doppler echocardiography and RVEFs measured with radionuclide vertriculography.Results Of the RVOT parameters,the right ventricular systolic time intervals(STI),velocity-time integral for ejection period (VTI),mean velocity (Vm) had a light correlation with RVEFs measured with radionuclide ventriculography.Conclusion RVOT parameters can not represent RVEFs,and is unable to reflect right ventricular systolic function in patients with pulmonary heart disease.
