Control of heart fibrillation using chaotic synchronization

Abstract

Chaotic conditions of the human heart causes arrhythmia. Once started, it can lead to death if left uncontrolled. To retain normal heart rhythm, chaos control through synchronization can be applied. A non-linear equivalent circuit for simulating heart behavior is suggested and tested. It is based on a set of differential equations that models heart dynamics. The obtained simulation results were consistent with those obtained rigorously. They have also demonstrated the effectiveness of the suggested technique in enforcing the heart to resume a structurally stable limit cycle state. The described synchronization technique has proven to be applicable to all heart arrhythmia, including fibrillation, bradycardia and even cardiac arrest. The controller designs described here can lead to the development of future smart clinical pacemakers.
