Conclusions The results showed that the value of blood output of heart in the rapid ejection period measured by the non linear formula may reflect the basic rule of the ejection of heart. 结论非线性公式计算心脏快速射血期的排血量和时间参数能够反映心脏射血的基本规律。
Results: All of the RVOT parameters, including acceleration time ( AT), ejection time ( ET), right ventricular systolic time interval ( STI), ratio of preejection period ( PEP) to AT ( PEP/ AT) showed statistically different between each two groups. 结果:RVOT血流参数加速时间(AT)、射血时间(ET)、右室收缩时间间期(STI)及射血前期(PEP)与AT之比值等,在两两组间均有显著性差异;
Results With the age increasing, the Vp, Qpi, Vp/ SV and P+/ P-of the rapid ejection period of heart decrease, furthermore, there were significant differences between the younger group and the older group ( P < 0.01). 结果心脏快速射血期的Vp、Qpi、Vp/SV以及P+/P-,随年龄增大而减小,且青年组与老年组之间有显著性差异(P<0.01);

Results Of the RVOT parameters, the right ventricular systolic time intervals ( STI), velocity-time integral for ejection period ( VTI), mean velocity ( Vm) had a light correlation with RVEFs measured with radionuclide ventriculography. 结果在RVOT血流参数中右室收缩时间间期(STI),射血期流速积分(VTI)和平均血流速度(Vm)与核素造影所测RVEF仅有轻度相关,其余测值无相关。
The quasi steady assumption was generally used in traditional theories for the gas ejection period. Some of the theoretical formulas have strange forms, and the physical meanings of these formulas are vague. 传统的后效期理论通常采用准定常假设,有些理论计算公式形式奇特,物理概念不清。
