Show Answers:

  1. Cardiac Glycosides/Cardiotonics
    -slows heart rate by decreasing conduction through the SA & AV node. Inceases the force of contraction (inotropic effect)

    treats CHF, AF, AFL, PAT (AKA SVT)

    -Ex: Digoxin
  2. Digitalis
    • Used to treat HF and SVT (AF)
    • -Slows down conduction
  3. Antiangial Drugs
    • 1.Calcium Channel Blockers
    • 2. Vasodilators
    • e. Beta-Adtenrgic Blockers
  4. 5 types of drugs for CAD
    • -Nitrates
    • -Beta Blockers
    • -Calcium Channel Blockers
    • -Statins
    • Anti-Platelets
  5. 3 Rate Control Atrial Fibrillation Drugs
    • Beta Blockers
    • Calcium Channel Blockers
    • Digitalis
  6. Antiangial Drugs

    Name the three types
    -treat chest pain (angina)

    • 1. Calcium Channel Blockers
    • 2. Vasodilators
    • 3. Beta-Adrenergic Blockers
  7. Calcium Channel Blockers
    block calcium across the cell causing dilation or coronary ateries and peropheral arteries
  8. Vasoidilators
    Relaxes smooth muscle layer of the blood vessels (dilation) =more blood flow

    Decreasre preload,afterload, and myocardial O2 consumption
  9. Beta Adrenergic Blockers
    • -Decrease activity of sympathetic nervous system
    • -decreases cardiac workload, excitability, slow conduction
  10. Classification of Antiarrhythmics
    • Class 1- blockers of fast soduim channels
    • Class 2- adrenergic blockers
    • Class 3- potassium channel blockiers
    • Class 4 - Calcium blockers
  11. Class I
    Subclass 1A
    • -cause moderate phase depress
    • -prolong repolarization
    • -increase duration of action potential
  12. Class I
    Subclass 1B
    • weak phase 0 depression
    • shorten depolarixation
    • decease action potention duration
  13. Class I
    Subclass 1C
    • strong phase 0 depression
    • no effect of depolarization
    • no effect on action potentional
  14. Class II
    • Beta Blockers
    • -blockage of myocardial receptors
    • -direct membrane stabilizing effects
  15. Class III
    • Potassium channel blockers
    • -cause delay in repolarization and prolonged refractory period

    *developed because on negative effects of calcium channel blockers
  16. Class IV
    • Calcium channel blockers
    • -slow rate of AV conduction in patients with atrial fibrillation
  17. Biggest problem with Antiarrythimc Drugs?
    Can cause arrhythmia!!!

    treatment of non-life threatening tachy may cause fatal ventricular arrhythmia
  18. Angiotensin-Converting Enzyme (ACE) Inhibitors
    • treat hypertension, CHF, post MI
    • lower blood pressure and volvume
    • reduces afterload
  19. Angiotension Receptor Blockers
    • Treats Hypertension, CHF, 
    • -causes vasodilation
    • -reduces afterload
  20. Analgesis
    -treats for chest pain

  21. Diuretics
    • Makes you PEE!!!
    • -used in heart failure/ fluid overload

    • Adverse affects-
    • hypotension
    • electrolytle imbalances
    • hyperkalemia
  22. Anticoagulants
    thin blood

    • Coumadin
    • Pradaxa
  23. INR
    Internationalized normalized ratio

    blood clotting time
  24. Thrombolytic Drugs
    used to dissolve blood clots and reopen blood vessles

    Activase (TPA)
  25. Antiplatelet Agent
    used after MI or stroke

  26. Antihyperlipidemics
    • -statins
    • treat  high cholesterol
  27. Atropine
    speeds up

    increases heart rate and cardiac output

    -bradycardia and asystole
  28. Adenosine
    slow down 

    Used in SVT

    slow heart rate and vasodialtes
  29. Inotropic
    increases/decreases the force of contraction
  30. Chronotropic
    Increases/decreases the rate contraction
  31. Dromotropic
    Increases/decrease rate of conduction
