Course Description: The 12-lead ECG Course is a 30-hour comprehensive course. For rhythms coverage, we recommend the Animated Rhythms Course. It is recommended that, if time permits, the participant read the first 129 pages of the Textbook (12-lead ECG Interpretation for the Medical Personnel) before beginning the online portion of the 12-lead Course. This will aid in the approach which Dr. Stanley takes to the interpretation of the 12-lead ECG.

To start the course, click on the “Module 1…” heading to the left (side bar navigation) or below this text. When you have completed a given topic or section, you will see a green dot to the left of that topic to let you know you may progress to the next topic.

Important note: You will have to move through the course in a step-wise, “page-by-page” fashion. The course is intentionally designed to not allow you to skip over any online pages, questions or sections.

We encourage you to utilize our content and tech support when taking this course. Simply click the “Contact Us” link at the top of the homepage and enter your inquiry. Content questions are answered by Dr. Stanley directly.
