This ECG is from a man in his 40s who presented with dyspnoea, hypotension and hypoxia. There was no chest pain. A chest xray showed diffuse pulmonary infiltrates, in a pattern consistent with pulmonary oedema.

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 Personal contact details such as email addresses will not be published but may be used to email you in reply.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.
Answer the questions to calculate the rate!

Which method do you want to use to calculate the rate?

Answer the questions to calculate the corrected QT interval!

Which formula do you want to use to correct the QT interval for rate (QTc)?

Answer the questions to calculate the cardiac axis!

Is Lead I (not V1) positive, negative or isoelectric?

Is Lead aVF positive, negative or isoelectric?

This is a library of 2393 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.
