分析32例闭塞性肺动脉高压的肺阻抗血流图资料,并与右心导管检查相对照,结果表明闭塞性肺动脉高压的肺阻抗基本波形为多峰递增波,波峰延迟为其主要特点,延迟的程度与肺动脉压呈正相关。
Pulmonary impedance blood flow data of 32 patients with obstructive pulmonary hypertension were analyzed and compared with those of right heart catheterization. The results showed that the basic waveform of pulmonary impedance in patients with obstructive pulmonary hypertension was multi-peak increasing wave, and the peak delay was the main characteristic. Delayed Degree and pulmonary artery pressure was positively correlated.
