Risk appraisal by novel chaotic globals to HRV in subjects with malnutrition
(2014-01-01)
The aim of this study is to assess the risk of dynamical diseases in malnourished children. This is achieved by the application of novel chaotic global techniques to the RR-intervals of the electrocardiogram (ECG) in the ...
Improvement of heart rate variability after exercise training and its predictors in COPD
(W B Saunders Co Ltd, 2011-07-01)
Background: Current literature lacks solid evidence on the improvement of heart rate variability (HRV) after exercise training in patients with COPD.Objectives: We aimed to investigate changes in HRV after two exercise ...
Short-term Heart Rate Variability Analysis in Healthy Dogs of Different Ages
(2022-01-01)
Background: The modulation of heart rate by autonomic nervous system may be evaluated by the heart rate variability (HRV), which illustrates the fluctuations between RR intervals. To evaluate this analysis, the intervals ...
Heart rate variability in young men: Effect of overweight and physical inactivity
Physical inactivity, overweight and obesity are factors that contribute to the development of chronic non-communicable diseases, which cause 35 million deaths each year, equivalent to 60% of all deaths worldwide [1]. Regular ...
Nonlinear analysis of heart rate variability within independent frequency components during the sleep–wake cycle
(Elsevier Science, 2010-04)
Heart rate variability (HRV) is a complex signal that results from the contribution of different sources of oscillation related to the autonomic nervous system activity. Although linear analysis of HRV has been applied to ...
Impacto da desnutrição na modulação autonômica cardíaca em crianças
(2016-11-01)
Objective To compare the autonomic behavior between malnourished children and a control group using analysis of heart rate variability (HRV). Method Data were analyzed from 70 children who were divided into two groups: ...
Heart rate variability: short-term studies are as useful as holter to differentiate diabetic patients from healthy subjects
(Wiley, 2003)
BACKGROUND: The definitive incorporation of heart rate variability (HRV) as a clinical tool depends on the development of more confident techniques of measurement. The length of the studies is a critical issue. Whereas ...
Heart rate variability and maximum workload reached in the dynamic physical exertion test in elderly men
(2012-11-01)
Introduction: One of the benefits provided by regular physical activities seems to be the improvement of cardiac autonomic nervous system modulation. However, the role of physical activity as a determinant factor of the ...
A snoring classifier based on heart rate variability analysis
(2011-12-01)
The effect of snoring on the cardiovascular system is not well-known. In this study we analyzed the Heart Rate Variability (HRV) differences between light and heavy snorers. The experiments are done on the full-whole-night ...
