Abstract
The effect of McN-A-343 was studied by direct administration into the sinus node artery of dogs vagotomized at the mid-cervical level. McN-A-343 blocked sinus bradycardia caused by electrical stimulation of the right vagus, while bradycardia induced by administration of acetylcholine or nicotine into the sinus node artery was not modified.
