document: Simulation of cardiovascular physiology : the diastolic function -LRB- s -RRB- of the heart The cardiovascular system was simulated by using an equivalent electronic circuit . Four sets of simulations were performed . The basic variables investigated were cardiac output and stroke volume . They were studied as functions -LRB- i -RRB- of right ventricular capacitance and negative intrathoracic pressure ; -LRB- ii -RRB- of left ventricular relaxation and of heart rate ; and -LRB- iii -RRB- of left ventricle failure . It seems that a satisfactory simulation of systolic and diastolic functions of the heart is possible . Presented simulations improve our understanding of the role of the capacitance of both ventricles and of the diastolic relaxation in cardiovascular physiology
