| 摘 要： | 目的：本文研究先天性心脏病患者肺动脉血流频谱图形变化，并比较其与肺动脉压力之间的关系。方法：采用经胸超声心动图观察３３例先天性心脏病患者肺动脉血流频谱变化，并与右心导管测肺动脉压进行对照分析。结果：患者超声心动图肺动脉血流频谱峰值前移与肺动脉压力程度呈正比。当肺动脉收缩压＞１００ｍｍＨｇ时，肺动脉血流频谱呈细条型（即正向血流窄、小、峰值极度前移）。结论：肺动脉血流频谱呈细条型可做为半定量判断ＰＡＰｓ＞１００ｍｍＨｇ的客观指标

| Abstract: | Objective and Methods:To probe the relation between pulmonary blood flow spectrum and pulmonary pressure(PP),33 congenital heart disease patients were examined by echocardiography and catheterization.Results:The early peak spectrum occurrence positively related to the degree of pulmonary hypertension,PP>100mmHg make the spectrum pattern slender and extremely forward shifting.Conclusion:Slender pattern and early occurring pulmonary peak spectrum suggested PP usually greater than 100mmHg,a semiquantitative parameter might be established. |
