Abstract: The paper deals with an electromechanical model of liquid flow in a
tube in order to model blood flow in vessels. The present paper deals with
detailed mathematical development of a model based on the theory of electrical
long line with distributed elements. The detailed derivation of primary
parameters of the analogical electric circuit is described. There are presented
some results of application of the model like wave impedance and wave vector of
the blood pulse wave, which are important for the model application to the
blood vessels system diagnosis. The significant parameter of the pulse wave –
the pulse wave velocity (PWV) has been evaluated and the calculated values of
phase and group velocities in selected vessels have been confronted with
physiological data.
Keywords: Electromechanical analogy, electromechanical models, blood flow in vessels, simulation of physiological functions, mathematical methods in medicine, propagation of blood pulse wave, PWV
