Digital simulation of an electric shock performed by a direct and alternating current upon the impedance model of human body

U ovom je članku obrađen impedancijski model ljudskog tijela i fiziologija električnog udara na personalnom računalu, što do sada nije opisano u dostupnoj literaturi. Kao što je iz literature poznato, postoje vrlo velike poteškoće u određivanju električnih parametara kojima nadomještamo pojedine dijelove tijela, kako s obzirom na specifičnost svake ljudske jedinke, tako i na uvjete okoline za koje su parametri određeni. Budući da za takva eksperimentalna istraživanja ima dosta poteškoća, u radu je rađeno simuliranje na personalnom računalu na impedancijskom modelu, uz srednje vrijednosti parametara iz literature (8,10). Dobiveni rezultati imaju vrlo veliku podudarnost s eksperimentalnim rezultatima. Simuliranje dokazuje puno veću štetnost izmjeničnog napona i posebno pokazuje kolike se struje i naponi javljaju u okolini srca i na samom srcu, jer je ventrikularna fibrilacija srca jedan od najopasnijih popratnih pojava strujnog udara.In this study a model of the human body impedance and electric stroke physiology were elaborated on a personal computer. Until now this phenomenon has not been described in literature. It is known from literature that it is very difficult to determine electric parameters by which single parts of the body cauld be replaced, because of a high specificity of every human being as well as due to environmental conditions for which the parameters are determined. In this study, on the personal computer, the impedance model was simulated by mean levels of the parameters taken from literature. The results obtained were consistent with experimental results, and the approach to the problem was simplified. The simulation showed alternating voltage to be very harmful and pointed to the magnitude of currents and voltages adjacently to the heart, as one of the most dangerous phenomena accompanying electric stroke is ventricular fibrilation of the heart
