Question 1

what class is Adenosine?

Answer 1

Class V antiarrhythmic

Question 2

How does adenosine work?

Answer 2

It decreases the conduction of electrical impulse through the AV node and interrupts AV reentry pathways in paroxysmal supraventricular tachycardia

Question 3

Adenosine: 
Onset 
peak effects
duration
half-life

Answer 3

onset: 20-30 secs
peak effects: 20-30 secs
duration: 30 secs
half life: 10 secs

Question 4

Adenosine indication

Answer 4

tachyarrhythmias that refractory to vagal maneuvers (including narrow and wide tachs) and is diagnostic whether it is wide or narrow complex.

Question 5

Adenosine contraindications

Answer 5

Irregular rhythms such as A-fib and Torsades, 2nd and 3rd-degree heart blocks, asthma, sick sinus syndrome, and ppl who have known sensitivities.

Question 6

Adenosine Dosage

Answer 6

initial dose 6mg fast iv/io push, if more is needed next dosages are 12mg and 12mg. always followed with at least a 10 cc flush.

Question 7

what class is Amiodarone?

Answer 7

Class III antiarrhythmic

Question 8

How does Ami work

Answer 8

prolongs the action potential duration of ALL cardiac tissues. (affecting sodium, potassium, and calcium channel blockers)

Question 9

Indications for ami

Answer 9

life-threatening ventricular dysrhythmias such as v-fib and v-tach, can also be used for stable afib and stable narrow complex tachycardia. it is used to control rapid ventricular rate due to accessory pathway

Question 10

Ami contraindications

Answer 10

sinus brady, 2nd or 3rd degree av blocks, symptomatic bradycardia, or known hypersensitivity

Question 11

ami interactions

Answer 11

warfarin, digoxin, and procainamide

Question 12

Amiodarone dosage

Answer 12

Pulseless Vtach/Vfib: 300mg iv/io bolus followed by 150mg iv/io bolus for refractory arrythmia, max dose is 450mg

with pulses, 150mg iv/io over 10 mins
