Variability of Heart Rate in Obese Adolescents: An extensive Investigation

Physiology

The RR interval can be used to accurately predict HRV. Given their foundation in an electrocardiographic PQRST signature, they are prone to irregular behaviour. In the past, researchers often turned to statistical physics methods when studying such complex systems. Inexpensive, predictable, and non-invasive HRV monitoring of the sympathetic and parasympathetic branches of the autonomic nervous system is a growing field of study. HRV, or the human reverberation length, is a functional biomarker of ageing that has been studied extensively. Patients with "dynamical illnesses," such as epilepsy, COPD, diabetes mellitus, and others, may be requested to participate in the procedure alongside healthy volunteers in order to discover ANS-related events.
