  • The cardiovascular system with a lumped parameter model is treated,in which the Starling model is used to simulate left ventricle and the four-element Burattini & Gnudi model is used in the description of arterial system.Moreover,the feedback action of arterial pressure on cardiac cycle is taken into account.The phenomenon of mechanical periodicity (MP) of end diastolic volume (EDV) of left ventricle is successfully simulated by solving a series of one-dimensional discrete nonlinear dynamical equations.The effects of cardiovascular parameters on MP is also discussed.
