Cardiorespiratory Synchronization: is it a Real Phenomenon?

چکیده
In this work we present a quantitative approach to the analysis of cardiorespiratory synchronization, which is a newly discovered phenomenon. The primary aim of this stu+ is to determine whether cardiorespiratory synchronization is a real phenomenon or a random one. We utilized the surrogate data analysis approach. A surrogate data set was constructed ji-om recordings of ECG and respiration obtainedji-om 14 healthy adults. The surrogate data lacks the coupling between the heart and respiration. The real and surrogate data were subjected to a quantification algorithm in order to determine the statistical properties of synchronization in the two data sets. Synchronization was found in both the real and surrogate data. However, Synchronization was signlfcantly less abundant in the surrogate data. In view of those results, cardiorespiratory synchronization seems to be a real phenomenon, yet it probably does not play a crucial role in cardiorespiratory interaction.

Model for cardiorespiratory synchronization in humans.
Recent experimental studies suggest that there is evidence for a synchronization between human heartbeat and respiration. We develop a physiologically plausible model for this cardiorespiratory synchronization, and numerically show that the model can exhibit stable synchronization against given perturbations. In our model, in addition to the well-known influence of respiration on heartbeat, the...
متن کاملIndices of Cardiorespiratory Synchronization from Rat Blood Pressure Data
A recently developed method for the detection of phase synchronization between several oscillatory processes from one-dimensional signals has been extended to allow estimation of synchronization indices. It has been applied to blood pressure signals from freely moving rats. Each rat underwent four stages: 1) healthy; 2) healthy but challenged by beta-blockers; 3) with stress-induced myocardial ...

متن کاملStepwise transition to higher degrees of coherence in a random network of phase oscillators
We consider a model system of phase oscillators which are connected in a random network. The network favors the connection of oscillators with close values of phases. We extend the order parameter used in the study of synchronization of phase oscillators and define generalized order parameters for the model system. We investigate the equilibrium properties of the model and reveal a phenomenon o...
متن کاملEmpirical mode decomposition and synchrogram approach to cardiorespiratory synchronization.
We use the empirical mode decomposition method to decompose experimental respiratory signals into a set of intrinsic mode functions (IMFs), and consider one of these IMFs as a respiratory rhythm. We then use the Hilbert spectral analysis to calculate the instantaneous phase of the IMF. Heartbeat data are finally incorporated to construct the cardiorespiratory synchrogram, which is a visual tool...
