Abstract

Purpose: This study explores the use of heart rate variability (HRV) analysis, a noninvasive technique for assessing the autonomic nervous system, by applying nonlinear dynamics and chaos theory to detect chaotic behavior in RR intervals and assess cardiovascular health.

Methods: Employing the "System Analysis of Heart Rate Dynamics" (SADR) program, this research combines chaos analysis with the short-time Fourier transform to assess nonlinear dynamic parameters in HRV. It includes constructing phase portraits in Takens space and calculating measures of chaos to identify deterministic chaos indicators.

Results: The analysis identifies distinct chaos indicators in the cardiac rhythm of healthy volunteers compared to tachyarrhythmia patients, both before and after catheter treatment. Post-radiofrequency ablation (RFA) analysis shows promise as a predictive tool for arrhythmia recurrence.

Conclusions: The findings suggest that HRV analysis, through nonlinear dynamics, can be an effective noninvasive method for predicting arrhythmia recurrence following treatments like catheter ablation. This approach has the potential for early and precise detection of arrhythmia, pending further validation.

期刊介绍： Cardiovascular Engineering and Technology is a journal publishing the spectrum of basic to translational research in all aspects of cardiovascular physiology and medical treatment. It is the forum for academic and industrial investigators to disseminate research that utilizes engineering principles and methods to advance fundamental knowledge and technological solutions related to the cardiovascular system. Manuscripts spanning from subcellular to systems level topics are invited, including but not limited to implantable medical devices, hemodynamics and tissue biomechanics, functional imaging, surgical devices, electrophysiology, tissue engineering and regenerative medicine, diagnostic instruments, transport and delivery of biologics, and sensors. In addition to manuscripts describing the original publication of research, manuscripts reviewing developments in these topics or their state-of-art are also invited.
