用SJ-42型多道生理功能记录仪,测定了108名脑力劳动者坐位(SBA12~0)的心功能生理参数,得出以下正常值,SV61.1±17.1ml,CO3.99±1.07 1·min~(-1),CI2.35±0.651·min~(-1)·m~2,TPR1774±499dyn·s·cm~(-5)(177.4±49.4Pa·S·L~(-1)),MABP83.1±8.8(11.08±1.17kPa);B-Z51.3±7.9ms,Q-Z167.6±18.4ms,PEP116.0±17.5ms,LVET272.6±23.3ms.PEP/LVET0.43±0.08,EF58.8±10.6％,Hl11.3±2.7Ω·S~(-2),IRT93.6±11.6ms。分析了不同年龄组间的变异,提出了90％的正常值范围,STI的心率校正值回归方程式及STI指数值。
The SJ-42 multi-channel physiological function logger was used to measure the physiological parameters of 108 mental workers (SBA12 ~ 0). The following normal values were obtained: SV61.1 ± 17.1ml, CO3.99 ± 1.07 1 · Min ~ (-1), CI2.35 ± 0.651 · min ~ (-1) · m ~ 2, TPR1774 ± 499dyn · s · cm -5 (177.4 ± 49.4Pa · s · L -1 )), MABP83.1 ± 8.8 (11.08 ± 1.17 kPa); B-Z51.3 ± 7.9 ms, Q-Z167.6 ± 18.4 ms, PEP116.0 ± 17.5 ms, LVET272.6 ± 23.3 ms.PEP / LVET0 .43 ± 0.08, EF58.8 ± 10.6%, H1111 ± 2.7Ω · S ~ (-2), IRT93.6 ± 11.6ms. The variation among different age groups was analyzed. The normal range of 90%, regression equation of heart rate correction value and STI index value of STI were proposed.
