To research the alteration of pulmonary flow spectrum of patients with congenital heart disease and the relation between pulmonary flow spectrum and pulmonary artery pressure, 33 patients with congenital heart disease were examined by echocardiography and catheterization.
The result showed that the spectrum peak early occurring in patients with pulmonary hypertension and the degree of the spectrum peak early occurring was related to pulmonary artery pressure positively. The result suggested that when the pulmonary artery systolic pressure was over 100 mmHg, the flow spectrum showed slender pattern usually.
The slender pattern in pulmonary flow spectrum could be a semi-quantity parameter to predict that the pulmonary artery systolic pressure more than 100 mmHg.
为研究先天性心脏病患者肺血流频谱的变化以及肺血流频谱与肺动脉压之间的关系，对33例先天性心脏病患者进行了超声心动图和心导管检查。
结果显示，肺动脉高压患者频谱峰值提前出现，且频谱峰值提前出现的程度与肺动脉压呈正相关。结果提示，当肺动脉收缩压超过100 mmHg时，血流频谱通常呈纤细型。
肺血流频谱呈纤细型可作为预测肺动脉收缩压超过100 mmHg的半定量参数。
