Measurement

  • 1 small box = 1mm = 0.04 sec = 40 miliseconds
  • 5 small boxes = 1 big box = 5mm = 0.2 sec = 200 miliseconds
  • Entire ECG strip is ~10 seconds

Primary Analysis

Segments & Intervals

QTc <0.44 N/A

Axis

  • Cannot be measured if BBBs are present
  • If up in leads 1 and AVF then normal axis
