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 the heart. Furthermore, the width of Poincare plots can be considered as a criterion of short-term variability in heart rate signals. The hypothesis that Poincare plot indexes of heart rate variability (H...
متن کاملبکارگیری منحنیهای بازگشتی به منظور تحلیل سیگنالهای نرخ ضربان قلب در افراد با تجربه مدیتیشن
The current study analyses the dynamics of the heart rate signals during specific psychological states in order to obtain a detailed understanding of the heart rate patterns during meditation. In the proposed approach, we used heart rate time series available in Physionet database. The dynamics of the signals are then analyzed before and during meditation by examining the recurrence quantificat...
متن کاملbispectrum estimation of electroencephalogram signals during meditation
objective: electroencephalogram is a reliable reflection of many physiological factors modulating the brain. the bispectrum is very useful for analyzing non-gaussian signals such as eeg, and detecting the quadratic phase coupling between distinct frequency components in eeg signals.the main aim of this study was to test the existence of nonlinear phase coupling within the eeg signals in a certa...
متن کاملHeart rate dynamics during three forms of meditation.
OBJECTIVE This study was designed to quantify and compare the instantaneous heart rate dynamics and cardiopulmonary interactions during sequential performance of three meditation protocols with different breathing patterns. BACKGROUND We analyzed beat-to-beat heart rate and continuous breathing signals from 10 experienced meditators (4 females; 6 males; mean age 42 years; range 29-55 years) d...
متن کاملExaggerated heart rate oscillations during two meditation techniques.
We report extremely prominent heart rate oscillations associated with slow breathing during specific traditional forms of Chinese Chi and Kundalini Yoga meditation techniques in healthy young adults. We applied both spectral analysis and a novel analytic technique based on the Hilbert transform to quantify these heart rate dynamics. The amplitude of these oscillations during meditation was sign...
