摘要

摘要: 心血管系统是一个复杂的耦合系统,研究心脏和血管之间的相互作用有助于揭示心血管疾病的机理及发病规律。左心室的E(t)-R模型和体动脉树的T-Y管模型被用来研究心室-血管的动态耦合,得到了与生理实验符合得很好的结果。并详细探讨了各参数对心功能的影响及最优耦合问题,所得结果具有临床应用价值。

Abstract: Cardiovascular system is a complex interactive system.The study of ventriculo-arterial coupling can be greatly helpful to reveal the mechanism and regularity of cardiovascular system diseases.The dynamic process of the ventriculoarterial coupling is considered making use of E(t)-R model for the left ventricle and T-Y tube model for the arterial tree.The predicted pressure and flow wave-forms agree well with the experimental data.The effects of the SA and LV properties on the LV/SA function and the optimal coupling of ventriculo-arterial are also discussed.The results have clinical significance.
