Measurement

Grid.png

All these measures are valid for the standard paper speed of 25 mm/Sec

  • 1 small box = 1mm = 0.04 sec = 40 miliseconds
  • 5 small boxes = 1 big box = 5mm = 0.2 sec = 200 miliseconds
  • Standard 12 lead ECG duration = 10 seconds
Interval Time(s) Boxes
PR 0.12 - 0.20 3-5
QRS 0.06 - 0.10 1.5-2.5
QTc <0.44 N/A
