Objectives

At the conclusion of this training module the reader will be able to:

  • Recall the following:
    • Time is represented horizontally
    • Voltage/amplitude is represented vertically on the graph paper
    • Each small box has a time value of 0.04 second
    • Each large box has a time value of 0.20 second
    • Standard paper speed is 25mm/sec and can be adjusted
    • Standard calibration is 10mm/mV and can be adjusted
  • Recognize the difference between regular and irregular rhythms
  • Utilize proper method for determining heart rate
  • Properly describe P wave and recall the origin of the electrical activity
  • Accurately measure the PR interval and recall the normal range
  • Properly describe the QRS complex and recall what this electrical event represents
  • Accurately measure QRS complex and recall the normal range
