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 .
