<b>The effect of morphine on vagal inhibition of the heart: demonstration of dual atrioventricular nodal pathways</b> - DOI: 10.4025/actascihealthsci.v28i2.1102
Abstract
That electrical stimulation of the vagus decreased heart rate and increased the PQ interval in electrocardiogram, consistent with anterograde dual atriventricular conduction. The present experiments were investigating the interaction of the morphine with cardiac parasympathetic nervous control in dual atrioventricular node. Electrical stimulation of the vagus nerve induced significant bradycardia and of third degree atrioventricular block and the P wave appearance was negative in leads II. Because background anesthesia modulates the heart, administered morphine injection the P waves appearance was positive through one inhibitory action on atrioventricular nodal reentry. All suggest the presence of two functionally and anatomically distinct atrioventricular pathwaysDownloads
