作者导出的心阻抗图园台园柱体组合模型理论(包括数学上近似处理的胸围法)对阻抗图测定心输出量作了改进,校正了胸围,颈围个体差异,基础阻抗变异等对测定心输出量的影响,提高了测量的可靠性。但是,在心搏出量公式中,仍然采用了Kubicek的线性计算模式,即每心搏出量与心阻抗一次微分图的最大值、射血时间成正比。然而 The authors derive a cardiac impedance map of Park Bench Cylinder Combined Model Theory (including mathematically approximate treatment of the chest method) to improve the cardiac output measured impedance graph, corrected the bust, neck circumference, individual differences, the basic impedance variation of the determination The impact of cardiac output increases the reliability of the measurement. However, in the stroke volume formula, Kubicek’s linear calculation mode is still used, that is, the maximum value of the first derivative of the cardiac impedance and the ejection time are directly proportional to each cardiac output. however
