Antidysrhythmic Flashcards
1
Q
- It is a Class III antiarrhythmic.
- This is an Advanced Cardiac Life Support drug.
- K+ channel blocker - delays depolarization of heart (resting phase)
- Slows down conduction through QRS and ↓ firing of SA Node
- Can cause torsades de points (ventricular Tachycardia that winds around the baseline
- Class III anti-arrhythmic
A
Amiodarone
2
Q
Amiodarone Adverse Effects:
- pulmonary ______ (damaged lung disease)
- sinus arrest
- AV ______ (heart block)
- corneal micro-deposits
- thyroid dysfunction
- ____________ w/ grayish-blue skin deposits
A
fibrosis
block
photosensitivity
3
Q
- used for paroxysmal (abrupt onset) supra-ventricular (above the ventricles) rhythms
- ↓ automaticity in the SA node and slows conduction
- always given RAPID IV
A
Adenosine

- hypotension (LPB)
- ______ flushing
A
slow
facial
5
Q
________/Lidocaine

A
Qunidine/
Na+
Qunidine
6
Q
________/Diltiazem
- Class IV anti-arrhythmic
- Ca+ channel blocker (CCB)
- inhibits Ca+ influx in SA node
- used to slow rapid supra-ventricular rates
- IV fusion in ICU pts to ↓ HR

- edema
- hypotension (LBP)
- constipation
A
Verapamil/
heart
8
Q
Metoprolol/_________
- Class II anti-arrhythmic
- beta-blocker
- ↓ automaticity
- ↓ _________

A
/Propranolol
conduction
contractility
ventricular
