A Critical Review of Ultra-Short-Term Heart Rate Variability Norms Research

Frontiers in Neuroscience, 2020
Heart rate variability (HRV) is the fluctuation in time between successive heartbeats and is defined by interbeat intervals. Researchers have shown that short-term (∼5-min) and long-term (≥24-h) HRV measurements are associated with adaptability, health ...

Heart Rate Variability in Insulo-Opercular Epilepsy

Brain Sciences, 2021
Background: We aimed to evaluate heart rate variability (HRV) changes in insulo-opercular epilepsy (IOE) and after insulo-opercular surgery. Methods: We analyzed 5-min resting HRV of IOE patients before and after surgery. Patients’ SUDEP-7 risk inventory

Heritability of Ambulatory Heart Rate Variability. [PDF]

, 2004
Background - Reduced heart rate variability (HRV) is a prognostic factor for cardiac disease and cardiac mortality. Understanding the sources of individual differences in HRV may increase its diagnostic use and provide new angles for preventive therapy ...

How random is your heart beat? [PDF]

, 2006
We measure the content of random uncorrelated noise in heart rate variability using a general method of noise level estimation using a coarse grained entropy.

Circulating histones as clinical biomarkers in critically ill conditions

FEBS Letters, EarlyView.
Circulating histones are emerging as promising biomarkers in critical illness due to their diagnostic, prognostic, and therapeutic potential. Detection methods such as ELISA and mass spectrometry provide reliable approaches for quantifying histone levels in plasma samples.

Genome-wide association study of electrocardiographic and heart rate variability traits: the Framingham Heart Study [PDF]

, 2007
BACKGROUND: Heritable electrocardiographic (ECG) and heart rate variability (HRV) measures, reflecting pacemaking, conduction, repolarization and autonomic function in the heart have been associated with risks for cardiac arrhythmias.

Heart Rate Variability (HRV) and Pulse Rate Variability (PRV) for the Assessment of Autonomic Responses

Frontiers in Physiology, 2020
Introduction: Heart Rate Variability (HRV) and Pulse Rate Variability (PRV), are non-invasive techniques for monitoring changes in the cardiac cycle. Both techniques have been used for assessing the autonomic activity.

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.

From omics to AI—mapping the pathogenic pathways in type 2 diabetes

FEBS Letters, EarlyView.
Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.
