The baroreflex integrity in early-stage pulmonary arterial hypertension (PAH) remains
uninvestigated. A potential baroreflex impairment could be functionally relevant and possibly …

Introduction Baroreflexes and peripheral chemoreflexes control efferent autonomic activity
making these reflexes treatment targets for arterial hypertension. The literature on their …

Key points Dysfunction of post‐exercise cardiac autonomic control is associated with
increased mortality risk in healthy adults and in patients with cardiorespiratory diseases. The …

Background The purpose of this study was to evaluate the relationship between the breath-
holding duration and the sensitivity of the arterial baroreflex, as well as the prognostic value …

Increasing arterial blood pressure (AP) decreases ventilation, whereas decreasing AP
increases ventilation in experimental animals. To determine whether a “ventilatory …

We tested the hypothesis that activation of peripheral chemoreceptors with acute isocapnic
hypoxia resets arterial baroreflex control of both heart rate and sympathetic vasoconstrictor …

Sympathetic hyperactivity and parasympathetic withdrawal may cause and sustain
hypertension. This autonomic imbalance is in turn related to a reduced or reset arterial …

Background: Baroreceptor activation by a continuous infusion of phenylephrine selectively
abolishes the muscle sympathetic nerve activity (MSNA) response to hypoxia in humans …

Background: Chemoreflex-mediated sympathetic activation contributes to both initiation and
progression of chronic heart failure (CHF). Method: To study the direct role of increased …

Muscle sympathetic nerve activity (MSNA) exhibits well-described within-breath respiratory
modulation, but the interactive contributions of the arterial baroreflex remain unclear. The …
