  • Publication number: 20100234748
    Abstract: Method, system, and computer program method for detecting pathological fluctuations of physiological signals to diagnose human illness. The method comprises performing a sliding window analysis to find sequences in physiological signal data that match amplitude- and duration-adjusted versions of a template function to within a specified tolerance.

  • Publication number: 20100056940
    Abstract: The invention relates to a method for analysis of cardiac rhythms, based on calculations of entropy and moments of interbeat intervals. The invention provides an optimal determination of segments of data that demonstrate statistical homogeneity, specifically with regard to moments and entropy. The invention also involves calculating moments and entropy on each segment with the goal of diagnosis of cardiac rhythm. More specifically, an absolute entropy measurement is calculated and provided as a continuous variable, providing dynamical information of fundamental importance in diagnosis and analysis. Through the present invention, standard histograms, thresholds, and categories can be avoided.
