Baroreflex Sensitivity (BRS)

open access: yes
Baroreflex Sensitivity (BRS) assessment using an electrocardiogram (ECG). The baroreflex is part of the autonomic nervous system and helps to maintain the blood pressure at a constant level.

Physiological and autonomic responses to intermittent low‐lung‐volume apnoea and pain sensitivity: A randomized controlled pilot trial

open access: yesExperimental Physiology, EarlyView.
Abstract Intermittent apnoeas may induce hypoalgesia; however, the effects of low‐lung‐volume static apnoea have not been investigated. Eighty healthy participants were randomized to an apnoea group (AG) or a control group (CG). The AG performed a 6‐min protocol of intermittent static apnoea at low lung volume (passive exhalation), whereas the CG ...

Investigation of the arterial baroreflex mechanism as an automatic regulation system with a double-loop feedback

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2015
The arterial baroreflex mechanism as an automatic regulation system with two feedback loops is investigated. The approach for the evaluation of the vascular com.ponent of the baroreflex mechanism has shown.

Periosteal pressure sensitivity of the chest bone as a measure for autonomic function in ischemic heart disease

open access: yesFrontiers in Neuroscience
PurposeIn 177 patients with ischemic heart disease and elevated periosteal pain sensitivity of the chest bone indicative of autonomic nervous system dysfunction, we test the hypotheses, (i) there is an association between the tilt table responses for the

The cold‐water immersion recovery–adaptation paradox: Reconciling acute parasympathetic and analgesic benefits with chronic hypertrophy attenuation

open access: yesExperimental Physiology, EarlyView.
Abstract Cold‐water immersion (CWI) is among the most widely used post‐exercise recovery modalities in elite sport and clinical rehabilitation, yet a fundamental paradox now emerges from the evidence: the same protocols that accelerate parasympathetic reactivation and reduce perceived muscle soreness also suppress the molecular and cellular machinery ...

Role of 17beta-estradiol in the modulation of baroreflex sensitivity in male rats

open access: yes, 1998
Female mammals have an enhanced baroreflex sensitivity compared with their male counterparts, leading researchers to speculate that estrogen modulates autonomic tone.

Electrical Stimulation of Nucleus Tractus Soloitarii, Increase Baroreflex Sensitivity in Morphine Addicted Rats

open access: yesپزشکی بالینی ابن سینا, 2005
The previous studies have shown that the endogenous opiate system depress the baroreflex sensitivity in morphine dependent persons. Nucleus Tractus Soloitarii(NTS) is the main termination site of baroreceptor afferent neurons.

Baroreflex Sensitivity and Its Evolution During the First Year After Myocardial Infarction [PDF]

open access: yes, 1988
Experimental data have indicated that baroreflex sensitivity is often depressed in dogs after myocardial infarction and that this depression correlates strongly with subsequent mortality during episodes of acute myocardial ischemia.

Effects of ceiling fan use on cardiovascular autonomic function during simulated indoor overheating in bed‐resting older adults

open access: yesExperimental Physiology, EarlyView.
Abstract Older adults are at heightened susceptibility to heat‐related cardiovascular complications when exposed to indoor overheating. While ceiling fans are recommended as an accessible cooling intervention, their effects on cardiac autonomic regulation remain unclear.

Blunted Spontaneous Sympathetic Baroreflex Sensitivity in Young Healthy Black Men [PDF]

open access: yes, 2020
The prevalence and severity of hypertension in black individuals are greater than in any other racial/ethnic group in the United States. The arterial baroreflex dynamically regulates blood pressure (BP) on a beat-to-beat basis via alterations in cardiac ...
