Exaggerated expiration followed by deep inspiration may be triggering pulmonary stretch receptors eliciting the classic Hering-Breuer reflex, a vagally
mediated reflex that results in bradycardia and hypotension (1).
SDNN reflects global variability, while rMSSD is a measure of vagally
mediated heart rate oscillations.
Delayed sympathetically mediated vasomotor response to the initial loss of cardiac output after ventricular extrasystole produces systolic blood pressure overshoot that subsequently induces vagally
mediated late heart rate deceleration.
Deak et al., "TNF-[alpha]-induced corticosterone elevation but not serum protein or corticosteroid binding globulin reduction is vagally
mediated," Brain Research Bulletin, vol.
Studies have revealed that vagally
released acetylcholine (ACh) can induce [Ca.sup.2+] overload and facilitate activation of the atrial ACh-regulated potassium current UK>ACh), which results in abbreviation of the ERP and AF inducibility.
DC is strongly vagally
modulated, whereas HRT is driven by the baroreflex response.
(2000) results shows that heart rate was greater in the arithmetic task condition compared with the control voxels, condition, suggesting that the arithmetic task was associated with withdrawal of vagally
modulated slowing of heart rate.
Anticholinergic agents are effective bronchodilators for COPD because the disease is associated with increased vagally
GERD may cause cough through mechanical factors such as microaspiration, vagally
mediated cough reflexes, or neurally mediated bronchial inflammation.
The square root of the mean squared differences between successive R-R intervals (RMSSD) was selected as our estimate of vagally
Long-term facilitation of upper airway muscle activities in vagotomized and vagally
These drugs are effective for the treatment of vagally
induced bradycardia (19); however, they may increase the viscosity of secretions, which could plug narrow endotracheal tubes, especially in small birds.
