This ECG is from a man in his 70s who had just undergone an aortic valve replacement.
ECG Archives: Hours out of the OR for valve replacement surgery: patient with paced rhythm becomes hemodynamically unstable. Repeat ECG.
This ECG shows a ventricular paced rhythm with excessively discordant ST elevation in II, aVF and V4, as well as concordant ST elevation in V5 and V6. The cause was a 100% occlusion of the right coronary artery.
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 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 Personal contact details such as email addresses will not be published but may be used to email you in reply.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.

This is a library of 2397 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.
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.
