Circadian rhythm of heart rate and heart rate variability in pregnancy [PDF]
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.

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.

Postoperative effects of bariatric surgery on heart rate recovery and heart rate variability [PDF]
Kosin Medical Journal, 2022 Background Several studies have reported associations between obesity and autonomic dysfunction. However, little research has investigated the effect of bariatric surgery on heart rate recovery (HRR) in the treadmill test and heart rate variability (HRV)

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‐
