This ECG is from a man in his 60s who presented with fever and delirium. He has a history of renal failure, T2DM and cognitive impairment.
This ECG shows accelerated idioventricular rhythm with peaked T waves due to hyperkalemia.
This ECG is from a young man who presented shortly after a 45 min episode of palpitations, shortness of breath, chest pressure and presyncope. He was an athlete.
This ECG shows marked sinus bradycardia with AV dissociation by default (not AV block) with junctional escape beats.
This ECG is from a woman in her 20s who presented with palpitations for an hour.
This ECG shows a regular narrow complex tachycardia (SVT) with secondary ST segment changes due to the extreme rate (205 bpm).
This ECG is from a man in his 60s who presented with intermittent shortness of breath and chest pressure over the past few days. This was his initial ECG.
This ECG shows a regular narrow complex tachycardia around 200 bpm, without P waves, with marked ST elevation in inferior leads and ST depression in anterior leads and aVL. The cause was thought to be atrial flutter from newly started flecainide. He also underwent angiography and had stents inserted to the left circumflex and right coronary arteries.
This ECG is from a middle-aged man who presented with chest pain, tachycardia 130 bpm and BP 50/30. He was alert but cool and clammy. His background was unclear, but he mentioned chronic dyspnoea, 'cancer' and 'chest'. Fluids were started. This was his initial ECG.
This ECG is from a middle-aged man who presented with chest pain, tachycardia 130 bpm and BP 50/30. He was alert but cool and clammy. His background was unclear, but he mentioned chronic dyspnoea, 'cancer' and 'chest'. Fluids were started. This was his second ECG, on arrival at hospital.
This ECG is from a male of unknown age who presented with progressive weakness over 3 days, on a background of haemodialysis, cardiomyopathy, diabetes and hypertension.
This ECG shows wide QRS complexes with peaked T waves caused by hyperkalemia.
This ECG is from a man in his 40s who had a cardiac arrest out of hospital. He regained cardiac output on the way to the Emergency Department.
This ECG is from a man in his 50s who presented to the Emergency Department complaining of chest pain for 1 hour. He was an ex-smoker and had a history of hypertension and hypercholesterolaemia.
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.
