STUDENT LEARNING OBJECTIVES

At the completion of this online tutorial the student should be able to:

  • Define the unique characteristics of cardiac anatomy and electrophysiology
  • Describe the electrophysiology of the heart
  • Describe the appropriate utilization and application of a cardiac monitor to include defining the difference between 3,5 and 12 lead cardiac monitor
  • Recognize normal electrocardiogram waveforms
  • Recognize abnormal electrocardiogram waveforms
  • Identify life-threatening electrocardiograms and their underlying physiology
  • Discuss appropriate responses to life-threatening electrocardiograms

 

COURSE DESCRIPTION

 This online tutorial will educate the student in the basic anatomy and electrophysiology of the heart, instruct in the correlation between the heart's electrophysiology and graphical representations on an electrocardiogram and present how electrical functioning of the heart affects the mechanical pumping of the heart.

The course will also inform students in normal electrocardiogram wave forms, abnormal waveforms, and life-threatening waveforms. The course will also educate the students in appropriate responses to abnormal and life-threatening waveforms.
