Complexity assessment of ECG RR interval

Abstract

Physical load is very important and necessary for human organism and for its systems functionality. During bicycle ergometry work we can evaluate the functionality of the human organism. We looked for the complexity measure, which could integrally and simple evaluate organism reaction to physical load.We used ECG RR interval allometric relation and RR interval information dimension. We indicated, that the slope of ECG RR interval allometric relation and information dimension could be used as the RR interval complexity measures, defining all organism reaction to physical load.The study showed that young women RR interval complexity is higher, it means that all organism adaptation to physical load is better, different organism systems better interact together. Significant differences between load and recovery periods detected different adaptation complexity levels.

Assessment of coherence and complexity of cardiac signals

“…The study showed that, for example, the RR interval complexity of young women is higher, so it means that whole organism adaptation to physical load is better, and different organism systems better interact together. The significant differences between load and recovery periods were detected in different adaptation complexity levels [8].…”

“…Lopez-Ruiz et al suggested the estimation of complexity by using statistical methods [7]. Berskiene et al used ECG RR interval allometric relation and RR interval information dimension [8]. Authors indicated that the slope of ECG RR interval allometric relation and information dimension could be used as the RR interval complexity measures, defining the whole human organism reaction to physical load.…”
