Case study: Monitoring the effectiveness of aromatherapeutic breathing with heart rate variability biofeedback

Heart and Mind, 2021
Heart rate variability (HRV) can be used as an objective measure of mental health and workplace stress. Workplace stress is associated with poor performance and organizations desire optimal performance from employees.

Autonomic pain responses during sleep: a study of heart rate variability [PDF]

, 2011
The autonomic nervous system (ANS) reacts to nociceptive stimulation during sleep, but whether this reaction is contingent to cortical arousal, and whether one of the autonomic arms (sympathetic/parasympathetic) predominates over the other remains ...

Aging effect on cardiac sympathovagal activity in healthy males over seven decades using short-term heart rate variability analysis

National Journal of Physiology, Pharmacy and Pharmacology, 2022
Background: The autonomic nervous system (ANS), which governs practically all bodily processes, alters structurally and functionally as we age. Heart rate variability (HRV) studies are non-invasive, quantitative approaches to investigate the effects of ...

The effect of gag reflex on cardiac sympatovagal tone [PDF]

, 2012
Objectives: Heart velocity may be influenced by gagging. The medulla oblongata receives the afferents of gag reflex. Neuronal pools of vomiting, salivation and cardiac parasympathetic fibers are very close in this area.

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 ...

Di\v{s}imo: Anchoring Our Breath [PDF]

, 2018
We present a system that raises awareness about users' inner state. Di\v{s}imo is a multimodal ambient display that provides feedback about one's stress level, which is assessed through heart rate monitoring.

Heart Rate Variability in Newborns

Physiological Research, 2017
Heart rate (HR) and heart rate variability (HRV) in newborns is influenced by genetic determinants, gestational and postnatal age, and other variables. Premature infants have a reduced HRV. In neonatal HRV evaluated by spectral analysis, a dominant activity can be found in low frequency (LF) band (combined parasympathetic and sympathetic component ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

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

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.
