Summary

This study applied a new method to analyze heart rate variability (HRV) data, detecting synchronization between cardiovascular processes. Findings reveal varying interaction strengths and model applicability in healthy individuals.

Area of Science:

Cardiovascular Physiology
Nonlinear Dynamics
Biomedical Signal Processing

Background:

Heart Rate Variability (HRV) analysis is crucial for understanding cardiovascular regulation.
Detecting synchronization in physiological systems can reveal underlying dynamics.
Previous methods for synchronization detection from univariate data have limitations.

Purpose of the Study:

To apply a novel synchronization detection approach to human heart rate variability (HRV) data.
To investigate the behavior of angles in return times maps derived from HRV.
To assess the model's ability to describe interactions within the cardiovascular system.

Main Methods:

Application of a recently proposed synchronization detection method.
Analysis of angles in return times maps from univariate heart rate variability (HRV) data.
Modeling of interactions between cardiovascular system processes.

Main Results:

Weak interactions between cardiovascular processes were observed in many subjects, fitting the derived model.
Distinctive angle map structures, not captured by the model, appeared in some subjects due to strong interactions.
Synchronization between involved processes was frequently detected.
Instantaneous radii in the analysis were found to be disordered.

Conclusions:

The new method effectively detects synchronization in human HRV data.
Cardiovascular system interactions vary in strength, influencing model fit.
Synchronization is a common phenomenon in the cardiovascular system, detectable through HRV analysis.
