Reliability of Lagged Poincaré Plot parameters in ultra-short Heart Rate Variability series: Application on Affective Sounds.
The number of studies about ultra-short cardiovascular time series is increasing because of the demand for mobile applications in telemedicine and e-health monitoring. However, the current literature still needs a proper validation of heartbeat nonlinear dynamics assessment from ultra-short time series. This paper reports on the reliability of the Lagged Poincaré Plot (LPP) parameters - calcula...
متن کاملInformative Nature and Nonlinearity of Lagged Poincaré Plots Indices in Analysis of Heart Rate Variability
Lagged Poincaré plots have been successful in characterizing abnormal cardiac function. However, the current research practices do not favour any specific lag of Poincaré plots, thus complicating the comparison of results of different researchers in their analysis of heart rate of healthy subjects and patients. We researched the informative nature of lagged Poincaré plots in different states of...
متن کاملSensitivity of temporal heart rate variability in Poincaré plot to changes in parasympathetic nervous system activity
BACKGROUND A novel descriptor (Complex Correlation Measure (CCM)) for measuring the variability in the temporal structure of Poincaré plot has been developed to characterize or distinguish between Poincaré plots with similar shapes. METHODS This study was designed to assess the changes in temporal structure of the Poincaré plot using CCM during atropine infusion, 70° head-up tilt and scopolam...
متن کاملPoincaré plot of heart rate variability allows quantitative display of parasympathetic nervous activity in humans.
1. Time domain summary statistics and frequency domain parameters can be used to measure heart rate variability. More recently, qualitative methods including the Poincaré plot have been used to evaluate heart rate variability. The aim of this study was to validate a novel method of quantitative analysis of the Poincaré plot using conventional statistical techniques. 2. Beat-to-beat heart rate v...
متن کاملDefining asymmetry in heart rate variability signals using a Poincaré plot.
The asymmetry in heart rate variability is a visibly obvious phenomenon in the Poincaré plot of normal sinus rhythm. It shows the unevenness in the distribution of points above and below the line of identity, which indicates instantaneous changes in the beat to beat heart rate. The major limitation of the existing asymmetry definition is that it considers only the instantaneous changes in the b...
