ABSTRACT:
A method of converting apparently chaotic time series data to a visual texture which, when displayed, can be really analyzed empirically. Correlation plots of vectors derived from time series of heartbeat intervals are displayed in color, to reveal useful information. The invention is particularly useful in a hospital cardiac environment, where subtle changes in cardiac rhythm can, with the method of this invention, provide evidence of abnormal cardiac functions.
