What are the optimal electrode configurations for external cardiac pacing and defibrillation based on a 2D finite element torso model?
A 2D finite element computer model identifies optimal electrode placements for external cardiac pacing and defibrillation, highlighting the impact of organ resistivity on surface current density.
Fahy et al. (1987) studied Cardiac pacing and defibrillation. Electrode configurations vs. Homogeneous body model was evaluated on Electrode performance and surface current density distributions. A finite element computer model found the optimal pacing position is placing the driven electrode directly over the heart and the receiving electrode on the left lateral chest wall.
