Validity and Efficacy of the Elite HRV Smartphone Application during Slow-Paced Breathing
Sensors, 2023 Slow-paced breathing is a clinical intervention used to increase heart rate variability (HRV). The practice is made more accessible via cost-free smartphone applications like Elite HRV. We investigated whether Elite HRV can accurately measure and augment

Journal of Cardiovascular Development and Disease, 2023 Cardiac damage has been attributed to SARS-CoV-2-related pathology contributing to increased risk of vascular events. Heart rate variability (HRV) is a parameter of functional neurocardiac integrity with low HRV constituting an independent predictor of ...

Impact of instrumental music on heart rate variability in ardent music listeners
Research in Cardiovascular Medicine, 2021 Purpose: The autonomic nervous system serves as the final gateway by which music exerts a therapeutic effect on health and disease. The aim of the study is to find the effect of different instrumental music on heart rate variability (HRV) as a part of ...

Cold Pressor Response in High Landers Versus Low Landers [PDF]
Journal of Clinical and Diagnostic Research, 2014 Background: Native high landers face two main environmental challenges i.e. hypobaric hypoxia and low ambient temperatures. Both factors contribute to increased sympathetic stimulation and increased blood pressure.

From Mice to Mainframes: Experimental Models for Investigation of the Intracardiac Nervous System
Journal of Cardiovascular Development and Disease, 2021 The intracardiac nervous system (IcNS), sometimes referred to as the “little brain” of the heart, is involved in modulating many aspects of cardiac physiology.

Comparison of Spontaneous versus Paced Breathing on Heart Rate Variability at High Altitude [PDF]
Journal of Clinical and Diagnostic Research, 2018 Introduction: There is conflicting data at sea-level to suggest that Paced Breathing (PB) versus Spontaneous Breathing (SB) during short-term Heart Rate Variability (HRV) measurement improves data reliability.
