Frequently Asked Questions

What is ECGpedia?

ECGpedia is an free online electrocardiography (ECG) course and textbook. All content is freely accessible. Anyone can contribute to the website and changes are supervised by physicians.

Who are the people behind ECGpedia?

ECGpedia is an initiative of Cardionetworks.org, a non-profit foundation whose goal is to advance medical knowledge, especially in the field of cardiology. The main contributors are: Jonas S.S.G. de Jong MD, cardiology resident, author and moderator; I.A.C. van der Bilt, MD, cardiology resident, author and moderator; Tymen T. Keller MD, PhD, cardiology resident, author and moderator; Pieter G. Postema MD, cardiology research fellow, author and moderator; Rob Kreuger, medical illustrator of most of the drawings; and Bart Duineveld, medical student, helper with technical issues, animations and lay-out.

What is the relationship between ECGpedia and Wikipedia?

There is no relationship between ECGpedia and Wikipedia. Both websites use the same software and share the idea of open access to information. The founders of ECGpedia have chosen to build a separate website, since an encyclopedia format does not allow the course- like setup of ECGpedia. It would also be difficult to incorporate information like the De Voogt archive. Furthermore, the ECGpedia license is somewhat more restricted than the Wikipedia license: reference to the source is compulsory when information from ECGpedia is used.

When do I know enough to say that I can confidently interpret ECGs?

Of course, there is no definite answer to this question. However, the American College of Cardiology has published a list of abnormalities a professional should be able to recognize. It is advisable to go through this list at the end of the course in order to recognize areas that need your attention. Understanding every item on the list does not guarantee that you will make the right decisions in every clinical situation.
