Inotropes - CORRECT ANSWER✔✔-Increase or decrease the force of
| | | | | | | | |



myocardial contraction.
|




Chronotropes - CORRECT ANSWER✔✔-Increase or decrease heart rate.
| | | | | | |




Dromotropes - CORRECT ANSWER✔✔-Increase or decrease conduction
| | | | | | |



velocity.


Vasopressors - CORRECT ANSWER✔✔-Increase or decrease vascular
| | | | | | |



smooth muscle tone.
| |




Positive inotropes - CORRECT ANSWER✔✔-catecholamines, calcium,
| | | | | |



Milrinone (primacore), and digoxin
| | |




Negative inotropes - CORRECT ANSWER✔✔-beta-blockers, calcium
| | | | | |



channel blockers
|




positive chronotropes - CORRECT ANSWER✔✔-atropine, dopamine,
| | | | | |



dobutamine, epinephrine.
|

, negative chronotropes - CORRECT ANSWER✔✔-beta-blockers, digoxin,
| | | | | |



cardizem


positive dromotropes - CORRECT ANSWER✔✔-atropine,
| | | | |



sympathomimetics


negative dromotropes - CORRECT ANSWER✔✔-digoxin, verapamil,
| | | | | |



diltiazem


sympathomimetic agents (catecholamines) - CORRECT ANSWER✔✔-| | | | |



Stimulate B-1, B-2, and alpha receptors.
| | | | |




B-1 receptors - CORRECT ANSWER✔✔-inotropic, chronotropic, and
| | | | | | |



dromotropic effects. |




B-2 receptors - CORRECT ANSWER✔✔-smooth muscle relaxation which
| | | | | | | |



can result in vasodilation and a decrease in systemic vascular resistance
| | | | | | | | | | |



(SVR).


Alpha receptors - CORRECT ANSWER✔✔-vasoconstriction, increase in
| | | | | | |



SVR, increase in blood pressure; can cause decrease in CI due to the
| | | | | | | | | | | | |



increase in after load.
