Abstract
In a healthy state, the human heart beat shows an extensive spectrum and its attractor has a chaotic orbit. However, in a damaged state, fluctuations in the heart beat become periodical. An, Implantable Cardioverter / Difibrillator(ICD), along with an implanted pace maker unit in either the subcutaneous chest wall, or subpectoral or subcutaneous abdomen, or sub-muscles rectus abdomen serve to detect abnormalities as follows and eliminate them quickly. The abnormalities affected include : ventricular fibrillation(non-regulated electrical activity in a ventricle)and other arrhythmia, such as, ventricular tachycardia(VT)or supra ventricular tachycardia(SVT). There are two methods for detecting arrhythmia available with the present ICD. One is to investigate the heart beat or period, and the other is to investigate the electrocardiographic wave. However, the employment of these techniques, either singly or in combination doesn't always reach the accuracy that is needed. At first, this paper describes traditional analysis methods and the problems of ICD in brief. Subsequently, it covers the chaotic approach. Finally, the results suitable for real testing, as well as future topics, are given.
