Adenosine

u slow the heart down > and as the drug washes off, there is a reactive tachycardia, and we want to compare the perfusion if tchycardia and slow beart beant to diagnose if there is an ischemia

Question 4

which drug can be used in ventricular ectopic beats, as long as there is no structural heart disease? why?

Answer 4

Flecainide> class 1C

bc it is proarryhtmatic, it can cause proaryhtmatic ventricular tachyarrthmia & sudden death

Question 5

thats how we use it as a treatment in converting

Question 9

1B> Best post MI

Question 10

why should flecanide not be used alone in ATRIAL FLUTTER?

Answer 10

say in atrial flutter, the flutter is traveling around the atrium in a normal fashion at 340pbm, if i give them flecainide, and slow conduction at the tissue, i can then reduce the rate of the atrial flutter to 240 bpm, if that patient’s av node is very good, that 240 beats can make the ventricles go 240 betas!

so in atrial flutter we use FLecanide in combo with drugs that block AV node!

so the flutter cannot conduct to the ventricles

Question 11

what is NOT used in atrial arrthmias?

Answer 11

class 1B

Question 12

which drug has many many SE?

Question 17

what 2 drugs do we not prescribe together if there is preexisitng heart block on the ECG?

Answer 17
