- Conclusion PAWP can be reliably noninvasive estimated combining Doppler echocardiographic variables of mitral and pulmonary venous flow. 结论联系二尖瓣及肺静脉血流参数进行多元回归分析可较准确地估测PAWP。
- Objective To study the change and relationship between pulmonary venous flow(PVF)spectrum and left ventricular function in children with renal hypertension(RH). 目的 研究肾性高血压 (RH)患儿肺静脉血流 (PVF)频谱与左室功能的变化及关系。
- There were 7 patients of whom the ratio E/A was beyond 2,however,the index of DT,IRT ,S and S/D were lower than control persons in mitral flow and pulmonary venous flow. 有7例二尖瓣血流频谱E/A>2,DT,IRT值减低,肺静脉血流频谱S值显著减低,S/D值显著减低。
- Results The pulmonary venous flow patterns were recorded in 23 of 25 subjects with ASD.Continuous antegrade wave replaced normally occurring S and D waves in all ASD patients. 结果2例患者肺静脉血流显示不满意,其余23例患者术前肺静脉血流频谱的前向血流缺失正常时肺静脉血流的S波和D波,而表现为一连续的、较平坦的波形,其负向的A波也较正常时减小,部分患者A波甚至消失。
- It is relatively independent of loading condition.Especially in pseudonormal pattern it has important value in identification,particularly when pulmonary venous flow cannot be detected successfully. 结论:二尖瓣环e/a比率反映的是组织结构运动的变化，具有相对不依赖血流负荷的影响，在二尖瓣血流频谱假性正常化时，具有重要的鉴别价值；
