Numerical determination of the risk of cardiac ventricular fibrillation in humans from body currents with frequencies up to 1 MHz using outcomes of animal studies

摘要

Cardiac ventricular fibrillation (CVF) is a potential cause of death following electrical accidents occurring when the electrical activity of the heart is disrupted. In order to determine thresholds for CVF, cadaver and animal studies were carried out in the past, which are however limited e.g. in tissue's electric properties and the utilized probes properties. Currently executed simulations with high resolution anatomical body models traversed by body currents with frequencies up to 1 MHz will be used for the derivation of CVF thresholds and can therefore help to prevent injuries caused by electrical currents in the future.
