Is shown, that as against single-phase model of pulse hemodynamics (the theory of passive diastole), the expression of pulse component in formula of definition of stroke volume on chest rheography explains satisfactorily in the view of two-phase model (the theory of active diastole). The new original rheographic index of blood supply of a studied vascular zone--local fraction of cardiac output is offered. Calculation of the given parameter has much in common with calculation of quantitative definition with pulse component of stroke volume, but is calculated under more simple formula and can practically be used for any site of cardiovascular system.
结果表明，与脉冲血流动力学的单相模型（被动舒张理论）相比，从两相模型（主动舒张理论）的角度来看，胸部血流图中每搏输出量定义公式中的脉冲成分表达式能得到令人满意的解释。提出了一种新的、用于研究血管区域血液供应的原始血流图指数——心输出量的局部分数。该参数的计算与每搏输出量脉冲成分的定量定义计算有很多共同之处，但计算公式更简单，并且实际上可用于心血管系统的任何部位。
