[Participation of the cardiac sympathetic innervation in the occurrence of vagotomic and atropine tachycardia in anesthetized dogs].

The sympathetic nervous system's role in the post-vagotomy and atropin-induced tachycardia was studied in anesthetized dogs. Bilateral vagotomy was followed by 166% tachycardia while on exclusion of the heart sympathetic innervation (inderal or novocain injections into the right stellate...

Intravenous infusion of blood elicited tachycardia in anesthetized dogs with beta-receptor blockade (dogs with vagal efferents intact but cardiac sympathetic efferents blocked) and bradycardia in dogs with combined beta-receptor blockade and rhizotomy at T1 (dogs with vagal efferents intact...

Vasoactive intestinal polypeptide facilitates atrioventricular nodal conduction and shortens atrial and ventricular refractory periods in conscious and anesthetized dogs.

Our study was designed to determine the cardiac electrophysiological influence of vasoactive intestinal polypeptide (VIP) in conscious dogs. Dogs (n = 8) were chronically instrumented with arterial and venous catheters, cervical vagal cooling coils, and right atrial and right...

Development of autonomic control of fetal circulation.

Nuwayhid B, Brinkman CR, Su C, Bevan JA, Assali NS.
PMID: 235216
Am J Physiol. 1975 Feb;228(2):337-44. doi: 10.1152/ajplegacy.1975.228.2.337.

Development of parasympathetic and sympathetic reflexes controlling heart rate, vascular pressures, and blood flows was investigated in fetal lambs weighing 300-5,800 g (65-165 days' gestation). Cardiovascular responses to veratridine injections, atrial stretching, bilateral cervical vagotomy, and cholinergic blockade with...

Effects of beta-adrenergic agonists on splanchnic vascular volume and cardiac output.

The American journal of physiology

Chang PI, Rutlen DL.
PMID: 1683172
Am J Physiol. 1991 Nov;261(5):H1499-507. doi: 10.1152/ajpheart.1991.261.5.H1499.

The effect of beta-adrenergic agonists on splanchnic intravascular volume (SIV), measured with radionuclide imaging, and the subsequent influence of such volume changes on cardiac output (CO) were examined in 40 anesthetized dogs. Isoproterenol (6 micrograms/min) caused a decrease in...

Beta adrenergic blockade with propranolol and atenolol in the exercising dog: evidence for beta 2 adrenoceptors in the sinoatrial node.

Cardiovascular research

Friedman DB, Musch TI, Williams RS, Ordway GA.
PMID: 2822246
Cardiovasc Res. 1987 Feb;21(2):124-9. doi: 10.1093/cvr/21.2.124.

To test the hypothesis that beta 2 adrenergic receptors mediate the chronotropic more than the inotropic response to endogenous catecholamines the effects on the haemodynamic responses to exercise in dogs of the beta 1 specific antagonist atenolol were compared...

Beta-adrenergic activation of the renin-angiotensin system following alpha 2-, alpha 1-, or nonselective alpha-blockade in conscious dogs: no relation to the changes in blood pressure.

Journal of cardiovascular pharmacology

Saeed M, Holtz J, Sommer O, Kühne G, Bassenge E.
PMID: 6206326
J Cardiovasc Pharmacol. 1984 Jul-Aug;6(4):683-92. doi: 10.1097/00005344-198407000-00021.

We analyzed the role of the renin-angiotensin system following alpha 2-, alpha 1-, or nonselective alpha-blockade in an intact organism in which both postsynaptic alpha-adrenoceptor types contribute to adrenergic vasoconstriction. In conscious dogs, alpha 2-blockade (0.3 mg/kg rauwolscine, n...

The effect of cardiac denervation and beta-blockade on control of cardiac output in exercising dogs.

European journal of applied physiology and occupational physiology

PMID: 6686131
Eur J Appl Physiol Occup Physiol. 1983;52(1):62-8. doi: 10.1007/BF00429027.

Normal and cardiac denervated dogs, with an electromagnetic aortic flowprobe implanted at least 14 days before the experiments, ran at different speeds on a 25% graded treadmill. The experiments were carried out before and after blockade of betareceptors in...

[A role of the autonomic nervous system in alterations of blood pressure and heart rate induced by 1, 1, 1-trichloroethane (author's transl)].

An experiment was conducted to clarify effect of 1, 1, 1- trichloroethane (1, 1, 1-TCE) on blood pressure and heart rate, and to investigate the role of the autonomic nervous system in these responses. Adult mongrel dogs were anesthetized...

Reflex cardiovascular depression during unilateral lung hyperinflation in the dog.

Free PMC Article

We have examined whether lung hyperinflation in the anesthetized dog reflexly depresses cardiac output, stroke volume, heart rate, and blood pressure and whether these changes persist for more than a minute. To eliminate any mechanical restriction to venous return...
