  1. Mecahnisms of cardiac arrythmias
    • abnormal impulse formation
    • abnormal impulse conduction
  2. Anatomy of cardiac arrythmias
    • Ventricular arrythmias
    • Supra-ventricular arrythmias
  3. Two words that mean an abnormal increase in impulses from SAN, AVN ad PF
    Enhanced automaticity
  4. Abnormal automaticity in tissues that do not normally show it
    Triggered activity
  5. An impulse re-exites a part of the heart through which it already passed
    Re-entry
  6. Image Upload 2
    Partial conduction block
  7. SA node disease, beta blockers and hypothyroidism can cause this
    Sinus bradycardia
  8. What are symptoms of bradycardia?
    • Dizzyness
    • Dyspnea
    • Fatigue
  9. Pregnancy, atropine, thyroidtoxicosis can cause this
    Sinus tachycardia
  10. A beat which occurs during diastole of the previous beat
    • Premature beat
    • atrial
    • ventricular
  11. Ventricular premature beat is followed by this
    Fully comensatory pause
  12. Sudden onset and termination of heart rates over 200 beats/min
    SVT
  13. Why does VT cause weakness, dizzyness, and fainting?
    not enough blood is pumped to body
  14. This is another name for atria beating 300 times per minute
    Atrial flutter
  15. Atria that beat 350 times per minute in an irregular way
    atrial fibrillation
  16. Multiple ectopic foci can cause this
    atrial / ventricular fibrillation
  17. A guy has ventricular fibrillation. What will his pulse feel like?
    No pulse bud
  18. This kind of heart block makes the AVN delay longer
    1st degree
  19. This kind of heart block stops some impulses from passing through the AV node
    2nd degree
  20. This kind of heart block stops all impulses from passing through AV node
    3rd degree
  21. 3 or more beats of ventricular origin in row at a rate greater than 100 beats/min
    Ventricular tachycardia
