Is the normal heart rate chaotic?

George Moody

In its June 2008 issue, the editors of Chaos announced a new feature, "Controversial Topics in Nonlinear Dynamics". The first controversial topic to be aired is "Is the Normal Heart Rate Chaotic?". This project provides data to explore this question.

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…

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…

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…
