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

Interaction between Heart Rate and Heart Rate Variability [PDF]
Annals of Noninvasive Electrocardiology, 2014 Heart rate variability (HRV) is significantly associated with average heart rate (HR), therefore, HRV actually provides information on two quantities, that is, on HR and its variability. It is difficult to conclude which of these two plays a principal role in the HRV clinical value, or in other words, what is the HR contribution to the clinical ...

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.

Heart Rate Sharing at the Workplace [PDF]
Multimodal Technologies and Interaction, 2021 Augmenting online interpersonal communication with biosignals, often in the form of heart rate sharing, has shown promise in increasing affiliation, feelings of closeness, and intimacy. Increasing empathetic awareness in the professional domain and in the customer interface could benefit both customer and employee satisfaction, but heart rate sharing ...

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 ...
