  1. NSR
    • rate: 60-100
    • everything is normal
  2. Sinus arrhythmia
    • irregular rhythm
    • rate: ~60-100
  3. sinus bradycardia
    • <60 bmp
    • all else is normal
  4. sinus tachycardia
    • >100- ~150
    • all else is normal

    • >100
    • irregular most of the time
    • 3 different shapes of p wave
  7. arital fibrillation
    • controlled: < or = 100
    • uncontrolled: >100
    • no t or p waves. totally erratic
  8. atrial flutter
    • no base line
    • flutter waves can be sharp or rounded
    • report fwave - QRS ratio
  9. normal PR interval
    .12-.20 sec
  10. prolonger PR interval
    >.2 sec
  11. accelerated PR interval
    <.12
  12. Normal QRS
    < or = .1 sec
  13. Gray Area QRS
    .11-.12 sec
  14. abnormal QRS
    >.12 sec
  15. Atrial tachycardia
    • 140-250
    • p-waves hidden in t-waves
  16. PAC (premature atrial contraction)
    • early beat
    • QRS is followed by a pause
  17. nonconducted PAC
    • early p wave
    • no QRS follows
    • look for pause
  18. junctional rhythm
    • 40-60
    • no p waves
    • inverted p-waves before or after QRS
  19. accelerated junctional rhythm
    • >60-100
    • no p waves
    • inverted p-waves before or after QRS
  20. Juntional tachycardia
    • >100
    • no p waves
    • inverted p-waves before or after QRS
  21. 1 degree AV block
    • PRI >.2 sec
    • state underlying rhythm and then "with 1 degree AV block"
  22. 2 degree AV block Mobitz I
    • progressively lengthening of PRI with dropped beats
    • irregular rhythm
  23. 2 degree AV block Mobitz II
    • suddenly dropped QRS without prior lengthening of PRI
    • can be regular or irregular
    • PRI are consistant but can be longer than normal
  24. 3 degree AV block
    • no relationship between p waves and QRS complexes
    • no consistant PRI
    • QRS is narrow or abnormal
  25. PVC (premature ventricular contraction)
    • Originates in ventricles
    • QRS is wide bizarre
    • report underlying rhythm and how many and postition of PVCs
  26. Multifocal PVCs
    PVCs that dont look the same
  27. Unifocal PVCs
    PVCs that look the same
  28. Ventricular bigeminy
    1 PVC 1 PVC 1 PVC 1...
  29. Ventricular trigeminy
    1 2 PVC 1 2 PVC 1 2 PVC...
  30. ventricular quadrigeminy
    1 2 3 PVC 1 2 3 PVC 1 2 3 PVC...
  31. SA block
    • irregluar because of pause
    • each pause is the same as or exact multiple of the distance between two other R-R intervals (within + or - 2 small boxes)
  32. Sinus Arrest
    • pause of undertermined length
    • not same distance as other R-R intervals
    • escape pacemaker site takes over usually
  33. IVR (idioventricular rhythm)
    • 20-40
    • no P waves
    • QRS > or = .12 sec and bizarre
  34. AIVR (accelerated idoventricular rhythm)
    • >40-110
    • no p waves
    • QRS > or = .12 sec and bizarre
    • causes MI
  35. Venticular Tachycardia
    • >110
    • QRS is wide and bizarre
    • no p waves
    • can be sustained or non sustained
  36. Ventricular fibrillation
    • totally erratic appearance
    • can be coarse or fine fibrillation
    • #1 cause of cardiac arrest (heart stops pumping)
  37. Torsades de pointes
    • >110
    • "twist of points"
    • squigly line thing
  38. PJC (premature junctional contraction)
    • early beat
    • inverted p wave after
  39. RBBB criteria
    • check QRS first
    • look in V1 and V2 for R,R 1 wave
    • look in V5, V6 or lead I for slurred s wave
  40. LBBB criteria
    • check QRS first
    • look in V5, V6 or Lead I for blunted QRS
    • Look in V1-V3 for predominately negative QRS
  41. QTc
    QTc= QT/ square root of RR
  42. Normal QTc
    <.46sec in women and <.45sec in men
  43. dangerous QTc
    >.5 sec
  44. Overdirve suppression
    term means there can only be one pacemaker in the heart
  45. ectopic
    team means the pacemaker of the heart is outside the SA node
