【摘要】 本文依据56例慢性阻塞性肺病和肺心病人的右心导管资料,分析了右心收缩时间间期(RSTI)指标RICT、RPEP、RVET、RPEP/RVET与右心舒缩能中dp/dtmax、t-dp/dtmax,VCE10、Vmax,-dp/dtmax诸参数的关系,结果显示了二者之间有一定的相关性。还探讨了使用无创性方法可以检测的RSTI来定量反映不易广泛开展的右心舒缩性能指标的可行性。用多元逐步回归分析方法建立了五个计算右心舒缩性能指标的方程式,经F检验,其dp/dtmax、t-dp/dtmax、-dp/dtmax三个方程式有显著意义(P<0.05)。

【Abstract】 Analysing the relation between the irems of systolic time intervals of right ventricle RICT, RPEP, RVET, RPEP/RVET and the indices of contractilc and diastolic performance of right ventricle dp/dtmax, t-dp/dtmax, VCE10, Vmax, -dp/dtmax, according to the material of cardiac catheterization on 56 patients of chronic obstructive pulmonary disease and Cor pulmonale, significant correlation was demonstrated between them. The study of feasibility on detecting contractile and diastolic performance of right ventricle with systolic time intervals of right ventricle, which can be measured by noninvasive way with ease. Five equations for calculating the items of contractile and diastolic performance of right ventricle were set up by means of multifactor regression analysis. Three of them, dp/dtmax, t-dp/dtmax and -dp/dtmax were significant respectively through F-test (P<0.05).
