Updated CPSGT Quiz


Questions and Answers
  • 1. 
    • regular or irregular beat?
    • QRS complex narrow or wide?
    • P waves present?
    • duration of P-R interval?
    The P:QRS is a 1:1 ratio
  • 2. 
    • Sinus Bradycardis:
    HR< 40 bpm for ages 6-adult
    • Sinus tachycardia
    HR > 9 bpm
    • Asystole Cardiac Pauses
    > 3 sec in duration call 911 if seen, unless patient is moving
    • Wide Complex
    - how we see the electrical impulse wide = longer * 3 consecutive beats at a rate of > 1-- bpm with a QRS duration > 0.12 sec narrow = fast/shortened * 3 consecutive beats at a rate of > 100 bpm with a QRS < 0.12
    • Atrial Flutter - think shark tooth
    - no round shape/aggressive - HR 220-430 bpm - no PR interval
  • 3. 
    PLM Index:   # of movements / TST(hour) PLM Arousal Index:    # of PLM arousald / TST(hour)
  • 4. 
    TRT: Total Recording Time
    • From lights out to lights on
    TST: Total Sleep Time
    • Total recording time minuse total wake time
    • TRT - wake total = TST
    Sleep Latency, or Sleep Onset
    • Lights out epoch to first epoch of any sleep stage (not wake)
    REM Larency - REM Onset
    • From sleep onset to first epoch of REM Sleep
    WASO - Wake after sleep onset
    • Number of epochs awake from sleep onset until lights on
    Sleep Stage Distribution = % in sleep stage
    • time in each sleep stage divided by TST
    • TST / TRT = SSD X 100 = %
    Sleep Efficiency
    • TST / TRT 
    • looking for over 80% for a good sleep
