Junctional Arrhythmias

The flashcards below were created by user NurseFaith on FreezingBlue Flashcards.

  1. Junctional Arrhythmias come from:
    The AV junction/AV node
  2. Depending on the place of the irritable spot in the heart will determine:
    • What is stimulated first:
    • (ie: if it is on top, the atria will be stimulated)
  3. EKG indicating Junctional Arrhythmia
    P wave will be seen in very weird places (depending on what is stimulated first)
  4. Inverted P waves, Weird out of place P waves
    Premature Junctional Contraction
  5. If the atria is depolarized before the ventricle, what shows on EKG
    Inverted P wave (junctional!)
  6. If the atria and ventricle are depolarized simultaneously, what will be seen on EKG
    No visible P wave (hidden from QRS)

    (premature junctional contraction)
  7. If ventricles are depolarized before the atria, the EKG will show:
    • P wave following a QRS complex
  8. Premature Junctional Contractions are considered _____ and therefore are not treated
  9. _____ Toxicity can mess up SA Node
  10. Rate of 40-60bpm, Inverted P wave, Out of Place P wave
    • Junctional Escape Rhythm 
    • (av node is acting as pacemaker)
  11. Treatment of Junctional Escape Contraction
    • Assess signs/symptoms of low cardiac output
    • Push meds if you realize decreased cardiac output sx
  12. Rate of 60-100 bpm, Inverted P wave, Out of place P wave,
    Accelerated Junctional Rhythm
  13. An EKG that looks like a junctional rate but is so much faster is normally:
    Junctional tachycardia
  14. Rate of 100-180 bpm, Inverted P wave, misplaced p wave
    Accelerated Junctional Rhythm
