    1. Vital Signs
    2. Pediatric Vital Signs
  2. Interpretation: Estimate from EKG Tracing
    1. Count Complexes in a 6 second strip
      1. Multiply complex count by 10
    2. Interval between complexes
      1. Count large boxes (0.2 seconds) between complexes
      2. Divide 300 by box count: 300, 150, 100, 75, 60, 50
        1. 1 large box (200 ms or 0.2 seconds): 300 bpm
        2. 2 large boxes (400 ms or 0.4 seconds): 150 bpm
        3. 3 large box (600 ms or 0.6 seconds): 100 bpm
        4. 4 large boxes (800 ms or 0.8 seconds): 75 bpm
        5. 5 large box (1000 ms or 1.0 seconds): 60 bpm
        6. 6 large boxes (1200 ms or 1.2 seconds): 50 bpm
        7. 7 large box (1400 ms or 1.4 seconds): 43 bpm
        8. 8 large boxes (1600 ms or 1.6 seconds): 37 bpm
  3. Interpretation: Background
    1. Intrinsic Rates
      1. Atria: 75
      2. AV Node: 60
      3. Ventricle: 40
    2. Rough estimates to remember
      1. Infant: 160
      2. Preschool: 120
      3. Teen: 100
    3. Normal Heart Rate for age
      1. Infant: 100-160
      2. Toddler: 90-150
      3. Preschool: 80-140
      4. School-age: 70-120

  4. Interpretation
    1. Bradycardia: under 60 (adults, see pediatric range above)
    2. Normal Sinus Rhythm: 60 to 100 (adults, see pediatric range above)
    3. Narrow Complex Tachycardia
      1. Sinus Tachycardia: over 100
      2. Supraventricular Tachycardia
        1. Infants: over 220
        2. Children: over 180
        3. Adults: over 160

      1. Ventricular Tachycardia
      2. Supraventricular Tachycardia with aberrancy

heart rate (C0018810)

Definition (ICF) Functions related to the number of times the heart contracts every minute.
Definition (ICF-CY) Functions related to the number of times the heart contracts every minute.
Definition (MSHCZE) Frekvence, kterou se srdce stahuje (tepe), počet tepů udávaný obv. za 1 minutu. SF bývá v klidu mezi 60–90 údery za minutu, u trénovaných osob (sportovců) bývá nižší. Její zrychlení se označuje jako tachykardie, zpomalení jako bradykardie. SF můžeme přesně zjistit pomocí EKG. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI_CDISC) The number of heartbeats per unit of time, usually expressed as beats per minute. (NCI)
Definition (NCI) The number of heartbeats per unit of time, usually expressed as beats per minute.
Definition (MSH) The number of times the HEART VENTRICLES contract per unit of time, usually per minute.
Definition (CSP) number of times the heart ventricles contract per unit of time.
