Heart rate variability (HRV) is concerned with the analysis of the intervals between heartbeats. An emerging analysis technique is the Poincare plot, which takes a sequence of intervals and plots each interval against the following interval. The geometry of this plot has been shown to distinguish between healthy and unhealthy subjects in clinical settings. The Poincare plot is a valuable HRV analysis technique due to its ability to display nonlinear aspects of the interval sequence. The problem… Expand
Analysis of lagged Poincare plots in heart rate signals of women referred to meditation clinic
Poincare plots are commonly used to study nonlinear behaviour of physiologic signals. Analysis of Poincare plots for various lags can provide interesting insights into the autonomic control of theExpand
Poincaré plots as a measure of heart rate variability in healthy dogs.
Twenty-four-hour Poincaré plots in healthy dogs show a 'Y' pattern with subtle variations unique to the individual, which can be used as a surrogate for time-domain analysis of HRV but visual analysis of the pattern provides additional information. Expand

Novel feature for quantifying temporal variability of Poincaré plot: A case study
The Poincaré plot of RR intervals is one of the most popular techniques used in heart rate variability (HRV) analysis. The standard descriptors SD1 and SD2 of Poincaré plot represents theExpand
ECG Artifacts and Poincaré Plot based Heart Rate Variability
Abstract: The analysis of beat to beat fluctuations of heart rate known as heart rate variability (HRV) become a non-invasive clinical research tool to study the modulation that the autonomic Expand
Poincaré plot indexes of heart rate variability: Relationships with other nonlinear variables
High correlation between SD1/SD2 index and HE and DFA (α1) in both groups is verified, suggesting that this ratio can be used as a surrogate variable. Expand
An index related to the autocorrelation function of RR intervals for the analysis of heart rate variability.
The theoretical study shows that VRL is directly related to the autocorrelation functions of the RR series at larger lags, and this index is applied to RR intervals from an animal study of long-term exposure to particulate matter. Expand

Heart Rate Variability Assessment using the Poincare Plot Parameters during Sleep
A nonlinear Poincare plot method for heart rate variability (HRV) analysis is widely used to evaluate autonomic nervous system activity. However, during sleep, the Poincare plot parameters are notExpand


Application of the Poincaré plot to heart rate variability: a new measure of functional status in heart failure.
The Poincaré plot pattern has potential advantages in that it allows assessment of data which are grossly non-Gaussian in distribution, and is a simple and easily implemented method which can be used in a clinical setting to augment the standard electrocardiogram to provide 'real time' visualisation of data.

Numeric processing of Lorenz plots of R-R intervals from long-term ECGs. Comparison with time-domain measures of heart rate variability for risk stratification after myocardial infarction.
Both the density of the Lorenz plots and the conventional measures of HRV were used to investigate the differences among 48 patients who suffered an arrhythmic event during a 2-year follow-up period and the remaining 589 patients without arrhythmmic postinfarction complications. Expand
Quantification of Poincare' maps for the evaluation of heart rate variability
Poincare' plots (each normal RR interval is plotted against its next one) have been proposed for the study of heart rate variability. The plots submitted to independent observers for visual scoringExpand
Poincaré plot of heart rate variability allows quantitative display of parasympathetic nervous activity in humans.
The Poincaré plot is therefore a quantitative visual tool which can be applied to the analysis of R-R interval data gathered over relatively short time periods and strongly suggest that the "width' of the Poincare plot is a measure of parasympathetic nervous system activity. Expand
Reproducibility of short- and long-term Poincare plot parameters compared with frequency-domain HRV indexes in congestive heart failure
Poincare plot analysis allows a beat-to-beat approach of HRV detecting pattern resulting from non-linear processes not observable by other methods in a time- or frequency-domain analysis, suggesting that some parameters might be very useful in clinical setting. Expand
