  • 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.
