Fractal Thermodynamics of the States of Instantaneous Heart Rhythm

The paper considers the concept of fractal thermodynamics for studying the states of instantaneous cardiac rhythm (ICR) according to Holter monitoring (HM) data. An effective method cardiac rhythms analysis using the quantum phase space of the ICR Sq is presented. The space Sq is a powerful tool for studying nondeterministic chaotic systems which allows to identify statistical regularities adequately covering the patients’ cardiovascular system states in the context of nondeterministic chaos of ICR states [3, 4]. The results of our papers show with high accuracy Sq is a fractal. DOI 10.1134/S1061920821020096
