EKG Rhythms

  1. What possible dx IF:HR is normal, btwn 60 -100 bpm...
    • Normal sinus rhythm
    • A flutter
    • A-fib
    • 1° block
    • 2° block type I
  2. What possible dx IF:HR is too fast @ 101 - 150 bpm...
    • Sinus tach
    • A flutter
    • A-fib
  3. What possible dx IF:HR is WAY too fast @ 150+ bpm...
    • V-tach
    • SVT/A-tach
    • Torsade de pointes... fast but indeterminate rate
  4. What possible dx IF:HR is too slow @ 30 - 59 bpm...
    • Sinus brady
    • A flutter
    • A-fib
    • 1° block
    • 2° block type I or II
  5. What possible dx IF:HR is WAY too slow @ <30 bpm...
    • V. Fib (no rate)
    • Asystole
    • 3° block
  6. Non-shockable rhythms
    • Asystole
    • PEA
  7. Reg rhythms
    • Sinus reg/brady/tach
    • V-tach
    • SVT
    • A-flutter
    • 1* heart block
  8. Irregular rhythms
    • V-fib
    • 2* type 1 (winkie)
    • PAC
    • PVC
    • A fib
    • Torsade
  9. PVC
    • Premature ventricular contraction
    • WIDE QRS complex >120sec on EKG

    • card says no HR
    • Rhythm is irregular
    • There isn't a P wave right before wide QRS complex
    • So no relationship
  10. V tach
    • HR over >150
    • REGULAR rhythm 
    • No P wave, no QRS relationship
    • May or may not have pulse = PEA
  11. V-fib
    Lower chambers quivering, heart can't pump blood, causing cardiac arrest

    • No HR
    • Extremely irregular
    • Lethal, must be shocked quickly
  12. PAC
    Premature atrial contraction

    • Card says no rate
    • Irregular rhythm
    • P wave is premature and abnormal, may be hidden
    • QRS is narrow!
  13. SVT
    • A-Tach
    • *looks like T is humping P

    • HR >150, too fast
    • Regular rhythm
    • P is present, as is QRS, in relationship but moving way too fast

    • Treat: vagal maneuver, put face in water. 
    • Pharm: adenosine
  14. A-flutter
    • HR can vary: atria is at 240-350 bpm while ventricle varies
    • Irregular
    • No P wave, actually has F waves
    • Present/absent/present QRS
    • So no relationship

    Cardiovert
  15. A-fib
    Atria quiver at 350-650 bpm while ventricles vary slow to rapid

    • HR varies...
    • Irregular rhythm
    • No P wave
    • Narrow QRS, no relationship

    Cardiovert
  16. 1 Degree Block AV
    • Reg rhythm
    • P wave is present
    • QRS is present
    • There is a relationship
    • Problem is it is long distance... PR interval is long >20
    • sec

    Only tx if symptomatic
  17. 2degree Block AV, Type 1
    Wenchebach

    • Irregular rhythm
    • Irregular P wave
    • QRS is present

    • QRS is dropped occasionally (Happens in both 2degree blocks)
    • PR interval gets increasingly prolonged.. this is the one were P wave moves
  18. 2 Degree type II
    • regular rate, but weird
    • P and QRS are together, apart, together, apart

    tx: pacemaker
  19. 3* block
    • Complete heart block
    • HR too slow
    • Reg rhythm
    • P present
    • QRS present
    • But no relationship.
    • They both individually reg, but not reg together

    Tx: pacemaker
  20. Torsade de pointes
    • Rate is indeterminate
    • rhythm is irreg
    • no P waves, QRS are wide
    • Looks like V-tach but makes varying changes.. small, big, wide QRS.
