Q

Amiodarone (Cordarone, Pacerone)

Class

A

Antidysrhythmic (KCL Blocker)

1
Q

Amiodarone

Another Name

A

Cordarone

Pacerone

2
Q

Amiodarone (Cordarone, Pacerone)

Description

A

Antidysrhythmic that prolongs duration of the action potential and refactory period and relaxes smooth muscle, reducing peripheral vascular resistance and increasing coronary blood flow

3
Q

Amiodarone (Cordarone, Pacerone)

Indication

A

Life threatening ventricular and super-ventricular dysrhythmias, frequently atrial fibrillation

4
Q

Amioderone (Cordarone, Pacerone)

Contraindication

A

Cardiogenic shock, severe sinus bradycardia, advanced heart block

5
Q

Amiodarone (Cardarone, Paceron)

Dose/Route

A

150mg over 10 min pt w/ pulses
300mg pulseless IVP
Pedi: 5mg/kg IV/IO then 15 mg/kg/day

6
Q

Bretylium

Another Name

A

Bretylol

7
Q

Bretylol

Another Name

A

Bretylium

8
Q

Bretylium (Bretylol)

Class

A

Antidysrhythmic (KCL Blocker)

9
Q

Bretylium (Bretylol)

Description

A

Causes release of norepinephrine, depresses ventricular fibrillation and reduces ectopy. Suppresses ventricular tachydysrhythmias including vfib with reentry mechanisms

10
Q

Bretylium (Bretylol)

Indications

A

Ventricular fibrillation and ventricular tachycardia refactory to lidocaine

11
Q

Bretylium (Bretylol)

Contraindications

A

None

12
Q

Dose/Route

A

5mg/ kg IV then 10mg/kg /15-30 min to max 30mg/kg

13

Adenosine

Another Name

A

Adenocard

14
Q

Adenocard

Another Name

A

Adenosine

15
Q

Adenosine (Adenocard)

Class

A

Antidysrhythmic

16
Q

Adenosine (Adenocard)

Description

A

Can “chemically cardiovert” PSVT to normal sinus. Half life 10 seconds and does not cause hypotension

17
Q

Adenosine (Adenocard)

Indication

A

Narrow, complex paroxysmal SVT refactory to vegal maneuvers

18
Q

Adenosine (Adenocard)

Contraindication

A

Afib, 2nd-3rd degree heart block, sinus node disease, or asthma.

19
Q

Adenosine (Adenocard)

Precautions

A

May cause dysrhythmias especially asystole, COPD

20
Q

Adenosine (Adenocard)

Dose/Route
