Interaction between heart rate variability and heart rate in pediatric population.

Frontiers in Physiology, 2015
Background: Heart rate variability (HRV) is primarily heart rate (HR) dependent, and therefore, different HR may exert different impact on HRV. The objectives of the study were to evaluate the effect of HR on HRV in children and to determine whether HRV ...

Heart Rate Variability [PDF]

Hypertension, 2014
See related article, pp 1334–1343 In this issue of Hypertension , Monfredi et al1 address a phenomenon that has been repeatedly described in the literature2–5 but, nevertheless, went largely unnoticed by the scientific community using heart rate variability (HRV) to assess cardiac autonomic control or to predict cardiovascular health.

Aging effect on cardiac sympathovagal activity in healthy males over seven decades using short-term heart rate variability analysis

National Journal of Physiology, Pharmacy and Pharmacology, 2022
Background: The autonomic nervous system (ANS), which governs practically all bodily processes, alters structurally and functionally as we age. Heart rate variability (HRV) studies are non-invasive, quantitative approaches to investigate the effects of ...

Heart rate and heart rate variability in infants during olfactory stimulation

Annals of Human Biology, 2019
Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, ‘innate’ autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear.

Case study: Monitoring the effectiveness of aromatherapeutic breathing with heart rate variability biofeedback

Heart and Mind, 2021
Heart rate variability (HRV) can be used as an objective measure of mental health and workplace stress. Workplace stress is associated with poor performance and organizations desire optimal performance from employees.

Impact of Heart Rate Fragmentation on the Assessment of Heart Rate Variability

Applied Sciences, 2020
Heart rate fragmentation (HRF) is a type of sinoatrial instability characterized by frequent (often every beat) appearance of inflection in the R-R interval time series, despite the electrocardiograms appearing to be sinus rhythm.

Prevalence of 21 Physician‐Defined Severe Toxicities Following Childhood Acute Lymphoblastic Leukemia Treatment: Australian Retrospective Cohort Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall survival now surpassing 90% in developed countries. However, treatments are not without adverse effects. In this study, we apply the severe toxicity‐free survival (STFS) framework to determine the prevalence of 21 physician‐defined severe ...

Heart Rate Variability and Exceptional Longevity

Frontiers in Physiology, 2020
Centenarians are the paradigm of human extreme longevity and healthy aging, because they have postponed, if not avoided, mayor age-related diseases. The purpose of this study was to investigate potential differences in resting heart rate variability (HRV)
