Mid-anterior MI
A Mid-anterior MI causes ST elevation in aVL and V2. It occurs when there is an occlusion of a first diagonal branch of the LAD artery.

The delay between OMI and STEMI claims yet another patient’s anterior wall 30231
This ECG is from an elderly woman who presented with chest pain and shortness of breath.
This ECG shows ST elevation in V2 with hyperacute T waves in V2-3. Even though this does not meet STEMI criteria, it is highly suspicious. Serial troponins did rise, pain was ongoing and the ECG evolved to meet STEMI criteria. A 100% mid-LAD occlusion was found to be the cause. Echo showed widespread wall motion abnormalities and reduced ejection fraction.

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.
Comments & Feedback
This ECG Archive is an academic, non-commercial #FOAMed project aiming to crowdsource a free open access database of ECGs and signs. If you include your personal details such as your name in your feedback you will be attributed for your contribution, unless you tell us that you don't want this to happen. Personal contact details such as email addresses will not be published but may be used to email you in reply. Full project details and participant information available here.
