Acute Changes in Heart Rate Variability to Glucose and Fructose Supplementation in Healthy Individuals : A Double-Blind Randomized Crossover Placebo-Controlled Trial [PDF]

, 2022
SIMPLE SUMMARY: In this study, we investigated the cardio-autonomic stress responses to the ingestion of liquid glucose, fructose, a combination thereof and a placebo in healthy individuals at rest.

Heart Rate Variability and Cognitive Function: A Systematic Review

Frontiers in Neuroscience, 2019
Background: Autonomic dysfunctions may precede the development of cognitive impairment, but the connection between these dimensions is unclear. This systematic review aims to analyze the relationship between heart rate variability (HRV) and cognitive ...

Pulse rate variability in cardiovascular health: a review on its applications and relationship with heart rate variability

Physiological Measurement, 2020
Heart rate variability has been largely used for the assessment of cardiac autonomic activity, due to the direct relationship between cardiac rhythm and the activity of the sympathetic and parasympathetic nervous system.

Heart Rate Variability and Coronary Artery Bypass Grafting: A Systematic Review

Reviews in Cardiovascular Medicine
Background: Coronary artery bypass grafting (CABG) is a well-established surgical procedure used to treat significant coronary artery disease. Nevertheless, unfavorable cardiovascular events and complications, including cardiac arrhythmias may be ...

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

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.

Heart rate and heart rate variability in infants during olfactory stimulation

Annals of Human Biology, 2019
Background: Various plant odours have been shown to decrease heart rate and increase parasympathetic nervous activity. However, ‘innate’ autonomic responses without the influences of experience, assumptions and prejudices of odours remains unclear.

Real-Time Monitoring of User Stress, Heart Rate and Heart Rate Variability on Mobile Devices [PDF]

arXiv, 2022
Stress is considered to be the epidemic of the 21st-century. Yet, mobile apps cannot directly evaluate the impact of their content and services on user stress. We introduce the Beam AI SDK to address this issue. Using our SDK, apps can monitor user stress through the selfie camera in real-time. Our technology extracts the user's pulse wave by analyzing

Heart Rate Variability: New Perspectives on Physiological Mechanisms, Assessment of Self-regulatory Capacity, and Health risk

Global Advances in Health and Medicine, 2015
Heart rate variability, the change in the time intervals between adjacent heartbeats, is an emergent property of interdependent regulatory systems that operates on different time scales to adapt to environmental and psychological challenges. This article
