Higuchi fractal dimension applied to RR intervals in children with Attention Deficit Hyperactivity Disorder
(2016-01-01)
Background: Attention deficit hyperactivity disorder (ADHD) is categorized by a lowered attention span, recklessness, and hyperactivity. Autonomic nervous system inequality has previously been studied using the same data ...
Multidimensional and multiscale Higuchi dimension for the analysis of colorectal histological images
(2020-12-16)
Fracta1 techniques are widely explored to quantity and recognize texture patterns in digital images. Among the different types of fractal techniques, one that stands out is the Higuchi fractal dimension. The Higuchi fractal ...
Heart Rate Variability Analysis: Higuchi and Katz's Fractal Dimensions in Subjects with Type 1 Diabetes Mellitus
(2018-09-01)
Background and aims: Statistical markers are valuable when assessing physiological status over periods of time and in certain disease states. We assess if type 1 diabetes mellitus promote modification in the autonomic ...
Higuchi Fractal Analysis of Heart Rate Variability is Sensitive during Recovery from Exercise in Physically Active Men
(Mavera Edições Técnicas e Científicas Ltda, 2017-06-01)
OBJECTIVE: Nonlinear techniques to assess heart rate variability (HRV) have received much recent attention. We aimed to evaluate nonlinear HRV responses during recovery from exercise through the novel algorithm Higuchi ...
Higuchi fractal dimension applied to RR intervals during exposure to musical auditory stimulation
(2017-01-01)
Several musical genres have been demonstrated to encourage changes in cardiac autonomic modulation. So, we aimed to investigate the acute effects of auditory stimulation with heavy metal music by applying the Higuchi fractal ...
Comparativo de los Algoritmos de Dimensión Fractal Higuchi, Katz y Multiresolución de Conteo de Cajas en Señales EEG Basadas en Potenciales Relacionados por Eventos
(Fondo Editorial EIA - Universidad EIA, 2017-09-12)
La obtención de información por medio de la medición de señales registradas durante diferentes procesos o condiciones fisiológicas del cerebro es importante para poder desarrollar interfaces computacionales que traduzcan ...
Complex measurements of heart rate variability in obese youths: Distinguishing autonomic dysfunction
(2018-01-01)
Introduction: Heart rate variability (HRV) can be assessed from RR-intervals. These are derived from an electrocardiographic PQRST-signature and can deviate in a chaotic or irregular manner. In the past, techniques from ...
Chaotic analysis of heart rate dynamics after an exercise with flexible pole
(Mavera Edições Técnicas e Científicas Ltda, 2016-10-01)
INTRODUCTION: Exercises with a flexible pole have been applied in clinical practice for upper limb rehabilitation. Nevertheless, its acute effects on cardiac autonomic regulation are unclear.OBJECTIVE: To evaluate the acute ...
