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 ...

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 ...
