Addition of 24‐Hour Heart Rate Variability Parameters to the Cardiovascular Health Study Stroke Risk Score and Prediction of Incident Stroke: The Cardiovascular Health Study

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‐

An Overview of Heart Rate Variability Metrics and Norms

Frontiers in Public Health, 2017
Healthy biological systems exhibit complex patterns of variability that can be described by mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats called interbeat intervals (IBIs).

Impact of Heart Rate Fragmentation on the Assessment of Heart Rate Variability

Applied Sciences, 2020
Heart rate fragmentation (HRF) is a type of sinoatrial instability characterized by frequent (often every beat) appearance of inflection in the R-R interval time series, despite the electrocardiograms appearing to be sinus rhythm.

Effect of Somatic Experiencing Resiliency-Based Trauma Treatment Training on Quality of Life and Psychological Health as Potential Markers of Resilience in Treating Professionals

Frontiers in Neuroscience, 2018
Background: Individuals who treat trauma are at significant risk of vicarious traumatization and burnout. Somatic Experiencing® (SE®) is a resiliency-focused trauma treatment modality designed to address autonomic nervous system (ANS) dysregulation and ...

Heart rate and respiratory rate influence on heart rate variability repeatability: effects of the correction for the prevailing heart rate

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.
