Inferior ST depression

Inferior ST depression occurs in leads II, III and aVF. It is important to look for reciprocal changes, e.g. in aVL, which suggest acute coronary occlusion.

A man in his sixties with chest pain at midnight with undetectable troponin

This ECG is from a man in his 60s who presented with 3 hours of chest pain.

This ECG shows ST elevation and hyperacute T waves in V2 with inferior and lateral ST depression. The cause was acute LAD occlusion.

Anterior MI in paced rhythm, dismissed by cardiologist, patient died.

This ECG is from an elderly male who presented with chest pain. He has a pacemaker. This was his first prehospital ECG.

This ECG shows ventricular paced rhythm with concordant STE in aVR and concordant ST depression in II, III, aVF. The cause was most likely a proximal LAD or left main occlusion. This was missed and the patient died.

This is a library of 2395 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.
