Heart Rate Variability Modulates Interoceptive Accuracy
Frontiers in Neuroscience, 2021 Our emotional experiences depend on our interoceptive ability to perceive and interpret changes in our autonomous nervous system. An inaccurate perception and interpretation of autonomic changes impairs our ability to understand and regulate our ...

Heart-Rate Variability—More than Heart Beats?
Frontiers in Public Health, 2017 Heart-rate variability (HRV) is frequently introduced as mirroring imbalances within the autonomous nerve system. Many investigations are based on the paradigm that increased sympathetic tone is associated with decreased parasympathetic tone and vice ...

RapidHRV: an open-source toolbox for extracting heart rate and heart rate variability [PDF]
PeerJ, 2022 Heart rate and heart rate variability have enabled insight into a myriad of psychophysiological phenomena. There is now an influx of research attempting using these metrics within both laboratory settings (typically derived through electrocardiography or

Heart rate variability in male rats
Physiological Reports, 2023 The cardiovascular system is primarily controlled by the autonomic nervous system, and any changes in sympathetic or parasympathetic activity also have an impact on myocardial activity.

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

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 ...
