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…

Estimating Activity from Instantaneous Heart Rate

Using only a heart rate time series, it is possible to measure a number of features that reflect the level of physical activity. Here we provide software for deriving an "activity index" based on measurements of mean heart rate, total powe…

Long-term Recordings of Gait Dynamics

Stride interval fluctuations were studied in ten young, healthy men. Participants had no history of any neuromuscular, respiratory or cardiovascular disorders, and were taking no medications. Mean age was 21.7 years (range: 18-29 years). Height was …

Gait Maturation Database

The data contained here are from 50 healthy children ranging in age from 40 months to 163 months. Each data file is named with a subject identifier (1-50) and the subject's age (e.g., the file name 2-45.txt indicates that subject #2 is 45 months…
