Circadian rhythm of heart rate and heart rate variability in pregnancy
npj Women's HealthThe autonomic nervous system (ANS) regulates physiological changes during pregnancy, supporting fetal development and homeostasis. Heart rate (HR) and heart rate variability (HRV) are well-established, non-invasive biomarkers of ANS function.

Heart Rate Variability - A Historical Perspective [PDF]
Frontiers in Physiology, 2011 Heart rate variability (HRV), the beat-to-beat variation in either heart rate or the duration of the R-R interval – the heart period, has become a popular clinical and investigational tool.

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.

FUZZY LOGIC APPROACH FOR HEART RATE VARIABILITY
Journal of V. N. Karazin Kharkiv National University: Series Medicine, 2021 Intrioution. The heart rate variability (HRV) is based on measuring (time) intervals between R-peaks (of RR-intervals) of an electrocardiogram (ECG) and plotting a rhythmogram on their basis with its subsequent analysis by various mathematical methods ...

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 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 ...

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017 BackgroundHeart rate variability (HRV) characterizes cardiac autonomic functioning. The association of HRV with stroke is uncertain. We examined whether 24‐hour HRV added predictive value to the Cardiovascular Health Study clinical stroke risk score (CHS‐

MENTAL STATUS AND HEART RATE VARIABILITY [PDF]
, 2008 The results let us suppose that there are at least three periodical phenomena of HRV in frequency range related with mental status. Two of them have not been discovered and physiologically explained yet.
