A flattened ST segment is a subtle sign where the start of the T wave is less smooth and more abrupt than normal. This sign is nonspecific but can be associated with hyperkalemia or coronary disease, especially if seen in more than one lead.
This is a library of 2408 free, open access, re-usable ECGs from across the web.
Where did they come from?
These ECGs were collected from Free Open Access Medical Education (#FOAMed) blogs, with the permission of their authors. You can find out more about each ECG's source by clicking on it.
Why are they here?
This is an experiment in digital curation. The idea is to collect resources to increase awareness and accessibility. Over time, more ECGs in the collection will be tagged to make it easier to find them and reused in new interactive quizzes.
How can I use these ECGs?
You can use these ECGs for your own learning, teaching or research - as long as you abide by the terms of each ECG's copyright licence as stipulated by the original author.
