This ECG is from a man in his 30s who presented with chest pain and RUQ abdominal pain, on a background of type 1 diabetes. His BSL was high.
This ECG shows sinus tachycardia with a wide QRS, R in aVR, coved ST elevation and peaked T waves. The cause was hyperkalemia.
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 man in his 50s who presented with a high fever and dysonpea.
This ECG shows sinus tachycardia with widespread ST elevation. He was treated for sepsis but serial ECGs and troponins were abnormal. Angiogram showed a myocardial bridge in the mid LAD.
This ECG is from a man in his 60s who presented with abdominal pain dyspnoea and altered level of consciousness, in shock.
This ECG shows wide complex tachycardia with concordant ST elevation in V4-6, due to LAD occlusion. The rhythm was likely sinus tachycardia with RBBB and then LAFB mid way through the trace.
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.
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 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 an older woman who presented with dyspnoea, diaphoresis and chest pressure. She had a background of paroxysmal AF for which she was on flecainide.
This ECG shows a regular wide complex tachycardia with possible flutter waves. There was no response to adenosine. The patient was electrically cardioverted. The cause was thought to be flecainide toxicity.
This ECG is from a man in his 70s who presented with intermittent dyspnoea and chest pain over the past 2 weeks. He had a history of a pacemaker, heart failure, aortic stenosis, diabetes, hypertension, stroke, ischemic heart disease, chronic kidney disease and peripheral vascular disease. This was his initial ECG.
This ECG shows a wide complex tachycardia with ventricular pacing. The excessively discordant ST changes in V4-6 and aVR suggested diffuse subendocardial ischemia. He was found to have severe three vessel disease and a proximal left circumflex stenosis was stented.
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.
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.
