Filtering Poincaré plots

摘要: The Poincare plot (PP) is one of the many techniques used for ascertaining heart rate variability, which in turn a marker activity autonomic system. plots are very simple to produce, but their preparation involves few fine points. This paper describes them, namely filtering data plot. We show correct way data, present results not or incorrect and demonstrate how proper helps extract interesting information from data. A algorithms preparing plots, calculating PP descriptors included. As Matlab’s programming language unquestionable standard analysis medical sciences, we illustrate these by snippets code this language.
