The complexity quantification of physiologic signals is a field of considerable importance since loss of complexity has been proposed as a generic feature of pathological systems. This paper investigates entropy of the preprocessed time series of different laboratory animals -normal and borderline hypertensive rats. The systolic blood pressure and heart rate were recorded before the stress, during...
Heart rate and blood pressure short-term variability analysis represent promising quantitative measures of the cardiovascular autonomic controls. The analysis includes traditional statistical analytical tools and a number of methods based on nonlinear system theory, recently developed to give better insight into complex HR and BP time series. These methods might reveal abnormalities that may not be...
