What is the differential of this very unusual ECG?

This ECG is from a young male who presented with a gun shot wound to the head.

This ECG shows tall peaked T waves and short QT. Potassium and calcium levels were normal. These findings are unusual but the cause may have been intracranial haemorrhage.

What is this tachycardia that alternates from wide to narrow to wide?

This ECG is from a patient in their 50s who presented unconscious and tachycardic after a seizure.

This ECG shows alternating wide and narrow complex tachycardias at the same rate, likely due to aberrancy.

Found comatose with prehospital ECG showing “bigeminal PVCs” and “Tachycardia at a rate of 156”

This ECG is from a patient with a history of diabetes who was found with a GCS of 4.

This ECG shows sinus rhythm with peaked T waves that were so narrow they were mistaken for separate QRS complexes. The cause was hyperkalemia due to acute renal failure.

This is a library of 2407 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.
