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 ventriculo-arterial coupling is considered making use ofE(t)-R model for the left ventricle and T-Y tube model for the arterial tree. The predicted pressure and flow waveforms 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.

Key words: transverse isotropy, rectangular plate, state space method, ventriculo-arterial coupling, T-Y tube model, impulse response function
