This ECG is from a man in his 50s who presented with syncope on a background of diabetes, opiate abuse and possible prior cardiac disease.
ECG Archives: Instructors’ Collection ECG : Syncope and tachycardia
This ECG shows a supraventricular tachycardia with evidence of P waves, left axis deviation and slightly wider QRS (106 msec) likely due to LAFB, tall QRS concerning for LVH and fragmentation in V2-4 suggesting prior MI.
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 Personal contact details such as email addresses will not be published but may be used to email you in reply.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 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.
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.
