A NUMERICAL MODEL OF EXTERNAL CARDIAC STIMULATION

摘要

The present work is focused on the electromagnetic numerical modelling of artificialrncardiac stimulation. A 2D model of transcutaneous defibrillation described and analysed..rnEach region of the domain was considered to be linear, time-invariant, isotropic, thernsubdomain conductivity being averaged over the tissue/organ volume. Specificrncharacteristics of each model were computed, analysed or estimated, such as the optimalrnposition of the external electrodes, the current density in the myocardium and surroundingrntissues, the potential variation in the nodes of the mesh, the spectrum of the currentrndensity, the equipotential lines etc. The results and the efficacy of the model were analysedrnfor final conclusions.
