This ECG is from a female in her 60s presented with chest pressure for 1 hour. She had a history of hypertension and smoking. She described the pain as a "buffalo sitting on my chest". She also described a "weird" sensation in her jaw for 1 hour prior to arrival, associated with lightheadedness and diaphoresis.
This ECG is from a 12 yr old male who presented to the Emergency Department following an episode of palpitations and near-syncope. He had no known past medical history.
This ECG is from a man in his 80s who presented with acute chest pain.
This ECG shows LBBB with concordant STE in II, V5 and V6 due to inferior and lateral MI.
This ECG is from a young man presented after a stab wound to the chest. Rapid ED diagnosis of cardiac penetrating trauma was made by ED ultrasound, and the patient went to the OR and had a wound to the right atrium repaired. There was no laceration of any coronary vessel. He did well. This ECG was recorded at day 3 because of tachycardia.
This ECG is from a man in his 40s presented with chest pain that woke him from sleep. He had similar chest pain last night which subsided, and he was able to go to sleep only to be awoken several hours later by recurrent pain. He had a history of hypertension.
This ECG is from a man in his 60s who presented with several weeks of diarrhoeal illness following overseas travel. He had a past medical history of ischaemic cardiomyopathy. His medications included warfarin, a beta-blocker, a PPI, an ACE inhibitor and diuretics.
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.
