Impedance rheopneumogram (IRP) and right heart Swan-Ganz catheter examinations were simultaneously carried out in 63 patients. Two equations for calculating after-exercise-pulmonary-pressure (PAPm) were obtained by stepwise regression analysis: 1) PAPm (kPa) = -1.40-0.88.InHs+8.30.(B-F)+5.78.Q-B/B-Y (r = 0.730, IRP is measured at rest); 2) PAPm(kPa) = 6.46-5.04.Hs/square root of R-R +4.35.Q-B/B-Y-19.34.(Q-C) (r = 0.648, IRP is measured after exercise). This is a new method for diagnosing latent pulmonary hypertension noninvasively.
对63例患者同时进行了阻抗流变肺图（IRP）和右心Swan-Ganz导管检查。通过逐步回归分析得到了两个计算运动后肺压（PAPm）的方程：1）PAPm（kPa）=-1.40-0.88.InHs+8.30.（B-F）+5.78.Q-B/B-Y（r=0.730，静息时测量IRP）；2）PAPm（kPa）=6.46-5.04.Hs/√R-R+4.35.Q-B/B-Y-19.34.（Q-C）（r=0.648，运动后测量IRP）。这是一种无创诊断潜在肺动脉高压的新方法。
