Protective effect of vagal stimulation on reperfusion arrhythmias in cats.
The role of the autonomic nervous system in modulating reperfusion arrhythmias is still unclear. Experiments with sympathetic denervation or alpha- and beta-adrenergic blocking agents have provided mixed results, while the effect of parasympathetic activation has not been investigated extensively. The effect of bilateral vagotomy and of vagal stimulation was studied, with and without attendant ...

متن کاملEffects of vagal stimulation on cesium-induced early afterdepolarizations and ventricular arrhythmias in rabbits.
BACKGROUND Previous evidence has shown that increased sympathetic tone enhances the cesium chloride (Cs)-induced early afterdepolarizations (EADs) and ventricular tachycardias (VTs). METHODS AND RESULTS We assessed the effects of vagal stimulation on Cs-induced EADs and ventricular arrhythmias in the rabbit heart. Monophasic action potentials (MAPs) of the left ventricular endocardium were re...
متن کاملVagal Stimulation in Dogs
We determined the effects of changing the spatial dispersion of acetylcholine release on the phase-dependent chronotropic responses to vagal stimulation in anesthetized dogs. We stimulated the vagus nerves with one brief burst of electrical pulses each cardiac cycle, and we changed the timing of the stimulus by a small, constant amount each cardiac cycle to scan the entire cycle. To vary the he...
متن کاملEfferent vagal nerve stimulation protects heart against ischemia-induced arrhythmias by preserving connexin43 protein.
BACKGROUND Myocardial ischemia (MI) leads to derangements in cellular electrical stability and the generation of lethal arrhythmias. Vagal nerve stimulation has been postulated to contribute to the antifibrillatory effect. Here, we suggest a novel mechanism for the antiarrhythmogenic properties of vagal stimulation during acute MI. METHODS AND RESULTS Under anesthesia, Wistar rats underwent 3...
