Heart rate and respiratory rate influence on heart rate variability repeatability: effects of the correction for the prevailing heart rate [PDF]
Frontiers in Physiology, 2016 Background: Since heart rate variability (HRV) is associated with average heart rate (HR) and respiratory rate (RespRate), alterations in these parameters may impose changes in HRV.

Donkey Heart Rate and Heart Rate Variability: A Scoping Review
Animals, 2023 Heart rate (HR) and heart rate variability (HRV) are commonly used physiological measures in animals. While several studies exist on horse HRV, less information is available for donkeys.

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 ...

Bone mechanical loading reduces heart rate and increases heart rate variability in mice [PDF]
Bone ReportsCardiovascular disease and osteoporosis are clinically associated. Bone adapts to mechanical forces by altering its overall structure and mass. In response to mechanical strain bone cells release signaling molecules and activate the nervous system.

Investigating asymmetry in fetal and maternal heart rate accelerations and decelerations [PDF]
Scientific ReportsThis study investigates the asymmetry in heart rate (HRA) during fetal development in the fetus and mother. R-R intervals from noninvasive fetal and maternal ECG signals from 102 pregnant women whose gestational age ranges from 20 to 40 weeks were ...

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

Anatomy of the Heart with the Highest Heart Rate [PDF]
Journal of Anatomy, 2021 ABSTRACTShrews occupy the lower extreme of the seven orders of magnitude mammals range in size. Their hearts are large relative to body weight and heart rate can exceed a thousand beats a minute. To investigate whether cardiac traits that are typical mammalian scale to these extremes, we assessed the heart of three species of shrew (genusSorex ...
