Cardio Pharm -- Arrhythmia Flashcards
bradycardia
drug used
atropine
atropine
class, MOA
class: anticholinergic
MOA: blocks action of Ach at the parasympathetic sites in smooth muscle
increases CO
atropine
indications
SE
CI
indication: bradycardia
SE: arrhythmia
CI: tachycardia
diltiazem
brand name class
Cardizem
calcium channel blocker/nondihydropyridine anti arrhythmic class IV - rate control
cardizem
MOA
inhibits Ca ion from entering slow channel of myocardium during slow channel during depolarization
causes negative inotrope (weakens cardiac contraction)
diltiazem indication
atrial fibrillation
atrial flutter
Cardizem
SE
AV block
bradycardia
edema
hypotension
dilitazem
CI
hypotension 2 or 3 degree AV block cariogenic shock decompensated heart failure sick sinus syndrome
metoprolol
brand name
class
Lopressor
beta blocker/antiarrythmic class IV
Lopressor
MOA
selective inhibitor of beta-1 adrenergic receptors
blocks beta receptors
metoprolol indication
atrial fibrillation
heart failure
HTN
Aortic Aneurysm
Lopressor
SE
hypotension
bradycardia
AV block
Lopressor
CI
hypotension 2 or 3 degree AV block cariogenic shock decompensated heart failure sick sinus syndrome
medications taken for AFib
diltiazem (Cardizem)
metoprolol (Lopressor)
medications taken for pulseless ventricular tachycardia or vFIB
epinephrin amioderone (cardorone)
epinephrine
class
MOA
Alpha/beta agonist
MOA: cardiac stimulus and constriction of skeletal and vascular muscle
epinephrine side effects
angina pectoris
MI
cardiac arrhythmia
CVA
hypertension
limb ischemia
localized bleaching
palpitations
suptraventricular tachycardia
vasoconstiction
v arrhythmia
ectopy and vFIb
amiodarone
brand name , class
Cardarone
anti-arrhythmic agent Class III
amiodarone
MOA
inhibits adrenergic stimulation
effects Na, K, Ca
prolonging the action potential and refractory period
decreases AV conduction and sinus node function
amiodarone
indication
cardiac arrest with pulseless VT or VF unresponsive to CPR
amiodarone SE
hypotension
bradycardia
AV block
ventricular tachycardia
asystole
aFib
torsades de pointes
VFIB
PE, hypersensitive pneumonitis, pulmonary fibrosis
amiodarone (Cardarone)
CI
sinus bradycardia
2 or 3 degree heart block
cardiogenic shock
