Heart rate influence on the QT variability risk factors [PDF]
, 2020 QT interval variability, mostly expressed by QT variability index (QTVi), has repeatedly been used in risk diagnostics. Physiologic correlates of QT variability expressions have been little researched especially when measured in short 10-second ...

Cognitive Reappraisal Moderates the Quadratic Association between Heart Rate Variability And Negative Affectivity [PDF]
, 2021 There is uncertainty as to how heart rate variability (HRV), an index of flexible physiological reactivity, relates to an individual’s tendency to experience negative emotions. Research suggests that high and low HRV may reflect maladaptive physiological

Hypothetical Control of Heart Rate Variability
Frontiers in Physiology, 2019 In the last three decades, the analysis of heart rate variability by nonlinear methods demonstrated the complexity of cardiovascular regulation. Additionally to the observations of periodic heart rate regulation by the autonomic nervous system, the long ...

Decreased Heart Rate Variability in COVID-19
Intensive Care Research, 2022 Purpose Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which primarily infects the lower airways and binds to angiotensin-converting enzyme 2 (ACE2) on alveolar epithelial cells.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

HEART RATE VARIABILITY IN DEPRESSED PATIENTS
Psychiatry and Clinical Psychopharmacology, 2021 Objective: There are conflicting results on the relationship between heart rate variability (HRV) and major depression. There is some research reporting decreased heart rate variability in depressed patients, which may result in increased cardiovascular
