Generalized Poincare Plots Analysis of Cardiac Interbeat Intervals in Heart Failure

In this work we applied generalized Poincare plots (gPp) analysis of interbeat intervals in patients with heart failure. More, we compared gPp with its nearest analogy methods based on existing extended Poincare plots techniques. Obtained results showed advantages of gPp method over usually used distanced (lagged) Poincare plots analysis. Only gPp has the potential of three-dimensional visualization of results with quantification of new multiscaling parameters. It is comparable with other methods only in two-dimensional planes where all methods showed a strong negative correlation between patterns of Pearson correlation coefficients and patterns of the SD1/SD2 ratio over the whole range of Pp orders (lags). These results could be used as the basis for further research in new standardization of multiscaling methods in heart rhythm analysis where it is important to follow the pattern of regulatory mechanisms dynamics which is related to the duration of RR intervals.

Automated summary

In this study, we applied generalized Poincare plots (gPp) analysis to analyze interbeat intervals in patients with heart failure, and compared it with other existing extended Poincare plots techniques. The results showed that gPp method has advantages over the commonly used distanced (lagged) Poincare plots analysis, as it has the potential for three-dimensional visualization of results and quantification of new multiscaling parameters.
