Groups of Signs
Variations: QRS complex
This ECG is from a woman in her 60s who presented in acute heart failure with dyspnoea and intermittent chest discomfort.
This ECG shows atrial fibrillation, LVH and diffuse ST-T changes.
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.
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 man in his 60s who presented with intermittent shortness of breath and chest pressure over the past few days. This was his repeat ECG after the rhythm changed.
This ECG shows a sinus tachycardia with ST elevation in inferior leads and ST depression in anterior leads and aVL. He underwent angiography and had stents inserted to the left circumflex and right coronary arteries.
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 baseline ECG for comparison.
This ECG shows a normal ECG.
This ECG is from a man in his 70s who presented with chest pain for the last 90 minutes, on a background of type 2 diabetes and hypertension.
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.
