Numerical simulation of the cardiovascular haemodynamics has become a useful tool of the surgeon who diagnoses cardiovascular diseases and recommends the way of their medical treatment. The numerical model of the cardiovascular system of pulsating type imitating the electrochemical and mechanical activity of heart muscle and being under a short-term baroreflex control has been implemented to diagnose more accurate a patient's haemodynamic profile. This model enables thus the simulation of the haemodynamic reaction due to the baroreflex response at various perturbations in the circulatory system. The haemodynamic behaviour of the cardiovascular system in the cases of the heart failure as a consequence of the left-ventricular hypocontractility, with the usage of the heart support device and the circulatory failure caused by haemorrhagic shock are demonstrated.
