Reflex control of the peripheral circulation
TLDR
The neural discharge from autonomic CNS neurons on the circulation is defined by three factors: the continuous influx of afferent neural impulses that originate in the cardiovascular system as well as in other tissues and other parts of the CNS.About:

Journal ArticleDOI
The usefulness of head-up tilt testing and hemodynamic investigations in the workup of syncope of unknown origin.
TL;DR: The tilt test is commonly a provocative tool in the workup of patients with recurrent syncope due to vasovagal ‐ vasodepressor reactions and other abnormalities of blood pressure regulation, and its usefulness is augmented by associated hemodynamic and blood volume evaluations.
Journal ArticleDOI
Abnormal skeletal muscle bioenergetics during exercise in patients with heart failure: role of reduced muscle blood flow.
TL;DR: The data indicate that forearm muscle metabolism during forearm exercise is altered in a subpopulation of patients with heart failure, suggesting that other mechanisms, such as alterations in mitochondrial population or substrate utilization, may be responsible.
Journal ArticleDOI
Selective impairment of baroreflex-mediated vasoconstrictor responses in patients with ventricular dysfunction.
TL;DR: Despite high baseline values for FVR, patients with left ventricular dysfunction developed vasoconstriction during intra-arterial infusions of norepinephrine, thereby excluding a nonspecific depression of vascular reactivity as the mechanism for abnormal responses to LBNP in patients with LVD.

Comparison of Cardiac Pacing with Drug Therapy in the Treatment of Neurocardiogenic (Vasovagal) Syncope with Bradycardia or Asystole
Jasbir Sra,Mohammad Jazayeri,Boaz Avitall,Anwer Dhala,Sanjay Deshpande,Zalman Blanck,Masood Akhtar +6 more
TL;DR: In patients with neurocardiogenic syncope associated with bradycardia or asystole, drug therapy is often effective in preventing syncope, whereas artificial pacing is not.

Reflex cardiovascular and respiratory responses originating in exercising muscle
D. I. McCloskey,Jere H. Mitchell +1 more
TL;DR: In anaesthetized and decerebrate cats isometric exercise of the hind limb muscles was elicited by stimulating the spinal ventral roots L7‐S1.1.
Journal ArticleDOI
Defective cardiac parasympathetic control in patients with heart disease.
TL;DR: Baroreceptor-induced slowing of heart rate in normal subjects was shown to be mediated by the parasympathetic nervous system since it could be abolished with atropine.
Journal ArticleDOI
Manoeuvres affecting sympathetic outflow in human skin nerves.
TL;DR: It was concluded that most manoeuvres had different effects in the two nerve types, thereby confirming earlier indirect evidence for selective regional control of the sympathetic outflow.
Journal ArticleDOI
Evidence for a central noradrenaline receptor stimulation by clonidine.
Nils-Erik Andén,Hans Corrodi,Kjell Fuxe,B. Hökfelt,Tomas Hökfelt,C. Rydin,Torgny H. Svensson +6 more
TL;DR: Clonidine increased the flexor reflex of spinal rats also after depletion of all known noradrenaline stores, indicating a stimulation of also central noradRenaline receptors.
Journal ArticleDOI
The reflex nature of the pressor response to muscular exercise.
TL;DR: In anaesthetized cats tetanic contraction of the hind‐limb muscles, elicited by stimulating the ventral roots L6—S1, caused a rise of arterial blood pressure, usually accompanied by small increases in heart rate and pulmonary ventilation: in decerebrate cats, all components of the response were much increased.
