Baroreflex effectiveness index: an additional measure of baroreflex control of heart rate in daily life.

open access: yes, 2001
In healthy subjects, progressive beat-to-beat increases or decreases in systolic blood pressure (SBP) ramps are not always accompanied by baroreflex-driven lengthening or shortening in pulse interval (PI) ramps, respectively.

Aldosterone blunts the baroreflex response in man

open access: yes, 1998
1. Recent animal evidence suggests that aldosterone, like angiotensin II, may possess detrimental autonomic modulating properties. Aldosterone has been shown to impair the baroreflex response in animal models.

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.

Table_1_Cardiovagal Baroreflex Hysteresis Using Ellipses in Response to Postural Changes.docx

open access: yes, 2021
The cardiovagal branch of the baroreflex is of high clinical relevance when detecting disturbances of the autonomic nervous system. The hysteresis of the baroreflex is assessed using provoked and spontaneous changes in blood pressure.

Yohimbine attenuates baroreflex-mediated bradycardia in humans

open access: yes, 2007
alpha-2 Adrenoreceptor stimulation profoundly augments baroreflex-mediated bradycardia presumably through parasympathetic activation. We tested the hypothesis that endogenous alpha-2 adrenergic tone mediates a similar response. In 10 healthy men (age: 33+

Assessing the Cardiovagal Baroreflex

open access: yes, 2007
Abrupt decreases and increases in systolic arterial blood pressure produce baroreflex mediated shortening and lengthening, respectively, of the R-R interval. This phenomenon, otherwise known as the cardivagal baroreflex, is best described by the sigmoid

Lateral parabrachial nucleus modulates baroreflex regulation of sympathetic nerve activity

open access: yes, 1998
Previous studies have demonstrated that the lateral parabrachial nucleus (LPBN) is an important site for descending modulation of baroreflex control of heart rate.

Cerebral blood flow links insulin resistance and baroreflex sensitivity.

open access: yes, 2018
Insulin resistance confers risk for diabetes mellitus and associates with a reduced capacity of the arterial baroreflex to regulate blood pressure.

Pulsatile pressure can prevent rapid baroreflex resetting

open access: yes, 1990
In a previous study [Am. J. Physiol. 255 (Heart Circ. Physiol. 24): H673-H678, 1988] we demonstrated that baroreflex responses decay (reset) to increased static sinus pressures, but with increased pulsatile pressure, responses are maintained.
