This ECG is from a very elderly woman who presented with shortness of breath, chest and back pain intermittently for several nights. It was relieved by isosorbide, but when she lost this medication she became worse. She had a background of CAD, ischemic cardiomyopathy and heart failure with an ICD in situ for primary prevention. On arrival she was hypoxic (SpO2 88%) with a good BP and HR 90, but improved on CPAP then BIPAP. This was her initial ECG.

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 Personal contact details such as email addresses will not be published but may be used to email you in reply.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 2409 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.
