RESUMO
Methods of topology and numerical parameters determination of electrode-bioobject-electrode equivalent circuit system was developed for electrocardiostimulants (ECS) operating under voltage source regime. It was established that in designing of ECS of the kind the rated value of load impedance be 200-300 omega. Empirical histograms and distribution law curves of RC-parameters of the mentioned equivalent circuit took into account the variability of these parameters both in patients and depending on the position of electrode heart as well.
