Abstract: DefibViz is a software tool for defibrillation simulation and the visualisation of the resulting voltage gradient induced throughout the human heart and torso. This paper presents an extension to DefibViz that provides functionality for the interactive placement of multiple sets of transthoracic electrodes of varying shape, size, and applied voltage. Such a tool may provide biomedical engineers with additional insight into the efficacy of multi-electrode configurations as compared to the single pair of electrodes used in conventional defibrillators.

Keywords: defibrillation simulation; multiple electrodes; visualisation; transthoracic electrodes; voltage gradient; human heart; human torso; biomedical engineering; multi-electrode configurations; defibrillators; defibrillator design; transthoracic defibrillation; cardiac arrest.
