Information-Based Similarity

IBS is a novel method for comparing time series based on linguistic analysis of "word" frequency and rank order statistics. It has been applied successfully in a variety of applications, including analysis of interbeat (RR) intervals, clas…

Multiscale Poincare Plots

Poincaré delay maps are widely used in the analysis of cardiac interbeat interval (RR) dynamics. To facilitate visualization of the structure of these complex time series, we introduced a methodology called multiscale Poincaré (MSP) pl…

Heartprints - A Dynamical Portrait of Cardiac Arrhythmia

As part of an effort to visualize and to understand the dynamics of cardiac arrhythmias with frequent ventricular ectopy, we have developed a new representational technique termed "heartprints." These heartprints are a combination of seven…
