  1. What is Class 1 and what are some examples?
    • Na Channel Blockers
    • Procainamide
    • Lidocaine
  2. What is Class 2 and what are some examples?
    Beta-Receptor Blockers
  3. What is Class 3 and what are some examples?
    • Potassium Channel Blockers
    • Amiodarone
    • Sotalol
  4. What is Class 4 and what are some examples?
    • Calcium Channel Blockers
    • Verapamil
    • Ditiazem
  5. Which Anti-Arrthymic drug has a long half life?
    Amiodarone
  6. Adenosine
    • 10 second half life
    • Vasodilate
    • Decrease HR
    • Decrease AV nodal conduction
    • Cholinergic effect
    • Treats SVT
  7. Atropine
    • Anticholinergic Drug
    • Blocks muscarinic drugs
    • Increase HR and AV nodal conduction
  8. Procainamide
    • Class 1 Anti-Arrhthmic drug
    • Sodium channel blocker
    • Creates reversible lupus related symptoms
  9. Lidocaine
    • Class 1 Drug
    • Sodium channel blocker
    • More toxic than Procainamide and rarely used
  10. What causes supraventricular tachycardia?
    Reentry
  11. Verapamil
    • Class 4 drug
    • Calcium channel blocker
    • Decrease contractility, HR, conduction velocity
    • Smooth muscle relaxation
    • Vasodilation
    • Alternative to adenosine in treating SVT
  12. Diltiazem
    • Class 4 drug
    • Calcium channel blocker
    • Decrease contractility, HR, conduction velocity
    • Smooth muscle relaxation
    • Vasodilation
    • Alternative to adenosine in treating SVT
  13. -dipines
    Arterial vasodilators
  14. A-Fib Therapeutic Goals
    • Control ventricular rate (IV diltiazem)
    • Terminate arrhythmia
    • Prevent recurrences
    • Prevent thromboembolism (stroke)
  15. What is an adverse drug reaction to a Class III antiarrhythimic drug?
    • V-tach or Torsades de Pointes
    • V-fib and death
  16. Treating Torsades de Pointes
    • Magnesium
    • Suppresses early afterdepolarizations
    • Terminates the arrhythmia
  17. How does the tx of magnesium work?
    • Decreases influx of calcium
    • Thus lowering the amplitude of Early Afterdepolarization
  18. Treating SVT
    • Adenosine
    • Verapamil
  19. Treating Bradycardia
    • Atropine
    • Dopamine
    • Epinephrine
  20. Treating V-Tach/ V-Fib
    • Amiodarone
    • Procainamide
    • Lidocaine
    • (Magnesium Sulfate - TdP)
