Autonomic function in patients with functional dyspepsia assessed by 24-hour heart rate variability
(Kluwer Academic/plenum PublNew YorkEUA, 2002)
Changes in the loading conditions induced by vagal stimulation modify the myocardial infarct size through sympathetic-parasympathetic interactions
(Springer, 2015-07)
In a previous research, we described that vagal stimulation increases the infarct size by sympathetic co-activation. The aim of this study was to determine if hemodynamic changes secondary to the vagal stimulation are able ...
Reduced cardio-respiratory coupling indicates suppression of vagal activity in healthy relatives of patients with schizophrenia
(Elsevier Inc, 2010-03)
Previous studies have observed reduced vagal modulation in patients with acute schizophrenia and their first-degree relatives, thus suggesting a genetic predisposition. To investigate vagal modulation, we analyzed the ...
The role of the vagus nerve in the generation of cardiorespiratory interactions in a neotropical fish, the pacu, Piaractus mesopotamicus
(Springer, 2009-08-01)
The role of the vagus nerve in determining heart rate (f (H)) and cardiorespiratory interactions was investigated in a neotropical fish, Piaractus mesopotamicus. During progressive hypoxia f (H) initially increased, ...
Influência da oclusão bilateral das artérias carótidas comuns sobre a atividade vagal
(1976-12-01)
The effects of carotid occlusion on parasympathetic activity were studied in anesthetized dogs submitted to beta adrenergic blockade. Modifications of the heart rate, before and after administration of atropine, were ...

Selective Vagal Denervation of the Sinus and Atrioventricular Nodes, Guided by Vagal Reflexes Induced by High Frequency Stimulation, to Treat Refractory Neurally Mediated Syncope
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Vagal Denervation and Neurally Mediated Syncope. A 15-year-old female patient presented with frequent episodes of vasovagal syncope refractory to non-pharmacological and pharmacological measures. Two tilt-table tests ...
Preischemic efferent vagal stimulation increases the size of myocardial infarction in rabbits. Role of the sympathetic nervous system
(Elsevier Ireland, 2012-03)
The vagal nerve stimulation (VNS) has been tested for the treatment of chronic heart failure in humans (Schwartz et al., 2008). However, many of the effects of parasympathetic stimulation in ischemic heart disease are still ...
Increased Expression of Angiotensin II Type 2 Receptors in the Solitary-Vagal Complex Blunts Renovascular Hypertension
(Lippincott Williams & Wilkins, 2014-10-01)
Angiotensin II increases and decreases arterial pressure by acting at angiotensin type 1 and type 2 receptors, respectively. Renovascular hypertensive rats exhibit a high level of activity of the peripheral and central ...
Conduction between left superior pulmonary vein and left atria and atria fibrillation under cervical vagal trunk stimulation.
(2012-01-04)
Objective: The effect of cervical vagal trunk stimulation on conduction between left superior pulmonary vein and left atria
and atria fibrillation have not been systematically studied. We attempted to investigate the ...
