Pharm cardiac Flashcards
class I (sodium is #1)
Na channel blockers
class I - salty CAB driver
1C
1A
1B
salty cab driver
1C (1 degree C is zero)
decreases slope of phase O (depolarization) the most, then A and B.
1C adverse effects (C, you can’t use it post MI)
can’t use post MI
1A adverse effects (A1 gives me headaches, lupus, and tornados)
cinchonism (headache), drug induced SLE (lupus) Td Pointes (Torsades de Pointe)
1B - best for what? (Be the best post MI)
best post-MI
1C, 1A, 1B pneumonic for adverse effects
CQUDPB -
class II (beta after alpha) - and what do they end in?
beta blockers (end in olole)
class II decreases (II times II is 4)
phase 4 depolarization
class II how to memorize - 4 letters
Beta, SA/AV, olol, AFib
class II adverse effects (2nd class HIC)
COPD exacerabtion, impotence, hypoglcemia
class III (3 potatoes)
potassium blockers
class III - potassium channel blockers.
prolong refractory period. delay repolarization.
class III adverse drug reactions (amor, check your TFT)
TdP (torsades)
PFT - pumonary
LFT - liver
TFT - thyroid
class IV (4 milk)
ca channel blockers
class IV - (calcium has 7 letters, 0+3+4 =7)
0, 3, 4 phase cardiac action potential (calcium has 7 letters, 0+3+4 =7)
class IV adverse effects (I have edema and constipation in my 4th class)
edema and constipation
quinadine (1A) - what is it used for? (Quin is a superhero flying through vents)
used for superventricular type atrial dysrthymias and ventricular dysrthymias
quinadine adverse effects (I’m going deaf from listening to Quin)
can cause emboli, aFib, tennitis
lidocaine (1B) - only for (can only numb the vents)
Note changes on EKG. Only for ventricular dysrhythmia
How to administer Lidocaine in an emergency? (IM having an emergency with lidocaine)
Give IV only (IM in an emergency). inactive in PO form.
lidocaine for local anesthesia, never given how?
NEVER given IV
lidocaine adverse effects (lido makes me lie down)
Drowsiness
Parasthesias, tremors, twitching, Seizures Slurred speech
Flecainide (1C) (Flec can be a superhero or a wolf)
used to treat supraventricular tachycardias, including AV nodal re-entrant tachycardia (AVNRT) and Wolff-Parkinson-White syndrome (WPW).
beta blockers do what? (Beta blood vessels)
relax Blood vessels
metroprolol adverse effects - and don’t use with what diagnosis? (COPD at the Met is bad)
COPD (asthma patients!), dizziness, fatigue, exercise intolerance
Amiodarone (Cordarone®) (class III) (Amor likes to fibs)
uses - Recurrent V-Fib (or tach) - emergency
A-Fib (oral)
