[I C 3; I D]. An atropine analog would block muscarinic receptors and thus block actions that are mediated by muscarinic receptors. Muscarinic receptors slow AV node conduction velocity, thus muscarinic blocking agents would increase AV node conduction velocity. Muscarinic receptors increase gastric acid secretion, constrict the pupils, mediate erection, and cause sweating (via sympathetic cholinergic innervation of sweat glands); thus, blocking muscarinic receptors will inhibit all of those actions.
