1
Q
What is a inotrope?
A
- A medication that affects the force of the hearts contractions
2
Q
Affect of positive and negative inotropes
A
- Increases (positive inotropes) or decreases (negative inotrope) the strength of the hearts pumping action
3
Q
Reasons for administering inotropes
A
- Heat failure
- Cardiogenic shock
- Post cardiac surgery
4
Q
3 examples of inotropes
A
- Dobutamine
- Milrinone
- Metoprolol
5
Q
What is a chronotrope
A
A medication that affects heart rate
6
Q
Affects of positive and negative chronotropes
A
- Increases (positive chronotrope) or decreases (negative chronotrope) the rate at which the heart beats.
7
Q
Reasons for administering chronotropes
A
- Bradycardia
- Tachycardia
8
Q
Example of a chronotrope
A
Atropine - positive
9
Q
What is a dromotrope
A
- A medication that affects the condition speed of electrical impulses through the heart
9
Q
Affects of positive and negative dromotropes
A
- Increases (positive dromotrope) or decreases (negative dromotrope) the speed of electrical conduction, which is important in managing arrhythmias and ensuring proper heart rhythm
10
Q
Reasons for administering dromotropes
A
- Arrhythmias - adjust conduction speed
- Atrial fibulation or flutter

12
Q
What is a vasoactive medication
A
- A drug that influences blood vessel tone, impacting blood pressure and circulation
13
Q
Affect of vasoactive medications
A
- Used to either constrict (vasoconstrictor) or dilate (vasodilator) blood vessels
14
Q
Reasons for administering vasoactive medications
A
