Registration Fee:    $15.00

Course Overview
Reading EKG rhythm strips can be intimidating for those unfamiliar with the electrical tracings of the heart. This educational program will first take the learner through the history of EKG development, followed by a discussion of cardiac function, anatomy, blood flow, standard lead placement, and how the electrical activity of the heart translates to EKG tracings. A systematic approach for interpreting EKG patterns will be introduced, followed by the study and interpretation of heart rhythms to assist the learner in the identification of normal, abnormal, and lethal EKG patterns.

Learners will be able to work at their own pace through the following chapters:

  1. Discovery of Electricity in Medicine and EKG Development
  2. Cardiac Anatomy and Physiology
  3. Cardiac Blood Flow and Electrical Stimulation
  4. Repetitive Patterns of the Heart
  5. Detection of Cardiac Electrical Activity
  6. Normal Cardiac Activity
  7. Understanding Standard EKG Paper
  8. A Standardized Approach to EKG Reading
  9. Putting it All Together: Practice Strips

Educational Objectives
At the conclusion of this educational activity, participants should be better able to:

  • Describe how cardiac function relates to electrical activity and translates to EKG patterns
  • Demonstrate the systematic steps for interpreting EKG rhythm strips
  • Identify normal, abnormal, and lethal EKG patterns
