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 ...

Correlation of heart rate recovery and heart rate variability with atrial fibrillation progression
Journal of International Medical Research, 2021 Objective To examine the combination of heart rate recovery (HRR) and heart rate variability (HRV) in predicting atrial fibrillation (AF) progression. Methods Data from patients with a first detected episode of AF who underwent treadmill exercise testing

Circadian rhythm of heart rate and heart rate variability [PDF]
Archives of Disease in Childhood, 2000 Measurements of heart rate variability (HRV) are increasingly used as markers of cardiac autonomic activity.To examine circadian variation in heart rate and HRV in children.A total of 57 healthy infants and children, aged 2 months to 15 years, underwent ambulatory 24 hour Holter recording.

Heart rate recovery after exercise: relations to heart rate variability and complexity
Brazilian Journal of Medical and Biological Research, 2002 Physical exercise is associated with parasympathetic withdrawal and increased sympathetic activity resulting in heart rate increase. The rate of post-exercise cardiodeceleration is used as an index of cardiac vagal reactivation.

Behaviour, heart rate, and heart rate variability in pigs exposed to novelty
Revista Brasileira de Zootecnia, 2016 In the present study, we investigated behavioural responses and determined parameters of heart rate variability (HRV) to elucidate a relative activation of autonomic nervous system (ANS) during baseline (10 min) and in response to potentially stressful ...

A pilot study of patch Holter electrocardiograph recordings in healthy cats [PDF]
Open Veterinary Journal, 2022 Background: A patch Holter electrocardiograph (P-Holter) is cordless, making it lightweight unlike the conventional Holter electrocardiograph (C-Holter). A P-Holter can also take continuous measurements. For up to 14 days without replacing the battery or

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.
