Abstract

The dynamics of cardiovascular rhythms have been widely studied due to the key aspects of the heart in the physiology of living beings. Cardiac rhythms can be either periodic or chaotic, being respectively related to normal and pathological physiological functioning. In paper, we analyze the dynamics of cardiovascular rhythms based on both the model-based approach. Using the time-varying adaptive observer for MIMO systems, we apply the adaptive observer to the parameter estimation method to the ECG diagnosis.
