Is the Normal Heartbeat Chaotic or Homeostatic?

Chaotic systems are nature variable, which serve as important mechanism for adaptability and flexibility, which is essential for dealing with table unpredictable constraint and environmental changes. This complex variability's have been analyzed in patients that preceded sudden cardiac death. The major dynamic results indicated that the heart rate lost its physiological variability's, minutes to months before the patient's death due to cardiac failure. Some cases revealed that the lost of normal dynamics was represented by an overall reduction in beat-to-beat variability, while other demonstrate high periodic, relatively low frequency (0.01-0.04 Hz) that sometime sustained oscillations patterns of unusual starts and abruptively stops. These non-linear changes are known as bifurcations. Similar patterns such as low frequency oscillations and loss of variability have been encountered in cardiac arrest survivors, high risk patients and fetal distress syndromes. With this projects would like to further study the chaotic aspects of the heart to help better understand the chaotic implementation involved within it. Further investigation in the chaotic physiological system of the cardiovascular system and some portions of the nervous system could further help prevent and facilitate early detections of such medical conditions as heart attacks. It would be greatly beneficial to be able to collaborate with HPD to obtain further EEG, EKGs and other physiological system monitoring in order to obtain a more accurate correlation with chaos and the human body. Variable theories will be implemented such as the ones mentioned in the report as well as other formulas and theories including graphical analyze graphs
