Effects of vagus simulation and of acetylcholine on myocardial contractility, O2 consumption and coronary flow in dogs.

چکیده
STUDIES on myocardial contractility and coronary flow during vagal stimulation have yielded inconsistent results. This may be due to the fact that in most studies heart rate was not maintained constant and both ventricular function and coronary blood flow are influenced by changes in heart rate. When heart rate was maintained constant, no change in myocardial contractility was found." In the present study ventricular function and coronary blood flow were measured during vagal stimulation with the heart rate maintained at a constant level.

The effects of halothane on the interactions between myocardial contractility, aortic impedance, and left ventricular performance. IV. Haemodynamic responses to vagus nerve stimulation.
The effects of electrical stimulation of the vagus nerves have been studied in anaesthetized dogs, before and after bilateral interruption of the cardiac sympathetic nerves. During constant heart rates, maintained by right atrial pacing, vagus nerve stimulation caused small but significant reductions of myocardial contractility, but these were minor compared with the effects of other negative i...
متن کاملEffects of coronary blood flow and perfusion pressure on left ventricular contractility in dogs.
The effects of changes in coronary blood flow and coronary artery pressure on left ventricular (LV) contractility were determined in 18 animals. Dogs on cardiopulmonary bypass provided isovolumetric LV contractions during controlled perfusion of the coronary circulation. Coronary venous efflux, myocardial oxygen consumption, peak LV pressure, LV dp/dt, and the forcevelocity relations of the LV ...
متن کاملRole of K+ATP channels in local metabolic coronary vasodilation.
ATP-sensitive potassium (K+ATP) channels have been shown to play a role in the maintenance of basal coronary vascular tone in vivo. K+ATP channels are also involved in the coronary vasodilator response to adenosine. The aim of this study was to determine the role of K+ATP channels in local metabolically mediated increases in coronary blood flow during cardiac electrical paired pacing without ca...
متن کاملAcetylcholine causes coronary vasodilation in dogs and baboons.
Intracoronary administration of acetylcholine or efferent vagal stimulation causes coronary vasodilation in dogs. However, in baboons it has been reported that intracoronary acetylcholine results in a fall in coronary blood flow and that stimulation of the vagi is without effect. The dose response of intracoronary acetylcholine and the effect of efferent vagal stimulation on the coronary circul...
متن کاملThe Role of Nitric Oxide and Prostaglandins in the Effect of Adenosine on Contractility, Heart Rate and Coronary Blood Flow in Guinea Pig Isolated Heart
It is a well-established fact that adenosine and its receptor subtypes (A 1 and A ) are involved in changes of contractility, heart rate and coronary blood flow (CBF) under different circumstances. This study was conducted to evaluate the role of nitric oxide and prostaglandins in development of these changes. For this purpose, Nitro-L-Arginine methyl ester (L-NAME), and indomethacin as inhibit...
