A computer model of the voltage field in a portion of the atria, with each box progressing in time up to 20 seconds after fibrillation begins. The authors discovered adjusting the duration and the smooth variation in time of the voltage supplied by defibrillation devices is a more efficient mechanism that reduces the energy needed to stop fibrillation by three orders of magnitude.
