Hi all. I’ve made the plunge and invested in an Oura Ring 4. Reason was, I lacked confidence in the HRV readings taken by my Visible App and armband each morning - I wanted to see in more detail what is going on overnight. It’s early days, but I’ve seen some very revealing trends (that I...

Wearable heart rate variability monitoring identifies autonomic dysfunction and thresholds for post-exertional malaise in Long COVID Twan Ruijgt, Anouk Slaghekke, Anneke Ellens, Kasper Janssen, Rob CI Wust Objectives Patients with Long COVID experience disabling fatigue, autonomic dysfunction...

Association between electrolyte supplementation and cardiac injury in long COVID-19 Xida Li, Lanfang Wu, Shuo Sun, Haojian Dong, Jianfang Luo [Line breaks added] Objective This study aimed to investigate the association between electrolyte supplementation and cardiac injury in long...

An Overview of Heart Rate Variability Metrics and Norms Shaffer, Fred; Ginsberg, J. P. 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...

Abstract Background and Objectives: Heart rate variability (HRV) is defined as a physiological variation in duration between sinus beats. The aim of this study was to research and analyze the HRV between various groups of patients. Materials and Methods: A retrospective study was conducted in...

Abstract Objectives It has been hypothesised that functional somatic disorders (FSD) could be initiated by sympathetic predominance in the autonomic nervous system as measured by low heart rate variability (HRV). Earlier studies on the association between HRV and FSD are small case–control...

Impact of long COVID on the heart rate variability at rest and during deep breathing maneuver Abstract While the majority of individuals with coronavirus disease 2019 (COVID-19) recover completely, a significant percentage experience persistent symptom, which has been characterized as Long...

It's an interesting toy and PEM is visible in the data it collects. It tracks steps per day (imprecisely), heart rate, stress level, body battery, sleep phases. I'm not sure what measurements the stress level and body battery are based on. The body battery is the measure that seems most...

Autonomic dysregulation in long-term patients suffering from Post-COVID-19 Syndrome assessed by heart rate variability Abstract Post-COVID-19 Syndrome (PCS) is a condition with multiple symptoms partly related to dysregulation of the autonomic nerve system. Assessment of heart rate variability...

The Bateman Horne Center have a one page guide to using HRV for monitoring in ME/CFS. https://batemanhornecenter.org/wp-content/uploads/2023/05/Heart-Rate-Variability-HRV.pdf It includes what is HRV, How to track HRV and

I'm new to an ME diagnosis (got it Dec 27, 2022, although I'd had ME symptoms since 1994 if not before) but not new to cardiac issues. I've had lots of testing as a result of chest pain while exercising (nothing wrong with my heart; in retrospect an ME symptom related to pushing myself too hard)...

Abstract The bio-psycho-social model highlights intra-individual and inter-individual interactions, including psychotherapy. The processing of these interactions within a person takes place, among others, in the central autonomic network (CAN). The CAN's autonomic output to the periphery can be...

Abstract In a previous study using mobile-health technology (mHealth), we reported a robust association between chronic fatigue symptoms and heart rate variability (HRV) in female patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This study explores HRV analysis as an...
