A chaosing circuit model for heart fibrillation

Based on the equations of Keener, a novel and simple circuit model capable of generating chaotic activities similar to those that can occur in the heart is presented. The circuit consists of two RC cells, a mono-stable multi-vibrator, and a pulse generator, and is suitable for VLSI design. PSpice simulations are run to verify its performance. This model could be used to examine the possible reasons for the existence of these activities in the heart and will hopefully help to eliminate these causes.
