Abstract :
The automatic implantable defibrillator delivers a shock directly to the heart. Optimal strategies for delivering these shocks were determined by studying a three-dimensional computer model of the electric fields produced by internal defibrillation electrodes. A finite-element technique was used to determine energy and current distribution in the heart for electrode configurations typically in use clinically. The model provides useful data on regional current and energy distributions.<>
