54. Atropine Sulfate: a. Decreases heart rate by depressing the SA note and AV node activity b. Increases heart rate and sinus node automaticity; improves AV conduction Decreases heart rate by altering impulses through conduction pathways; slows conduction; prolongs effective refractory period с. 55. Epinephrine Hydrochloride: a. Decreases heart rate by slowing conduction of the AV node and by lengthening the refractory periods. Decreases blood pressure by dilating coronary arteries b. Reduces ventricular dysrhythmias that may follow and MI c. Increases heart rate and force of cardiac contractions; increases coronary and cerebral blood flow.
