Definition
tachycardia

Term
| Cholinergicagents/parasympathomimetics bethanechol (Urecholine} |
|
Definition
| activate the parasympathetic nervous system either directly by binding to cholinergic receptors or indirectly by inhibiting the action of AchE, which prevents the destruction of endogenous Ach so it remains on the cholinergic receptors longer and prolongs its action. |

Definition
stimulates the sympathetic nervous system either by:
