Groups of Signs
Variations: Sinus Rhythms
This ECG is from an elderly woman who presented with sudden onset shortness of breath after months of inactivity due to a back injury.
This ECG shows sinus tachycardia with large inverted T waves, consistent with right heart strain. The cause was a very large PE.
This ECG is from a man in his 30s who presented with 2 days of positional left sided chest pain.
This ECG shows normal sinus rhythm with widespread ST elevation and PR depression. The diagnosis was pericarditis.
This ECG is from a man of unknown age who had cardiac stents placed 2 months ago.
This ECG shows sinus rhythm with QS-waves and ST elevation in V1-V3, with some terminal T-wave inversion. Serial troponins and angiography was normal.
This ECG is from a teenage male who presented with chest tightness and shortness of breath for 6 hours on a background of asthma.
This ECG shows sinus rhythm with tall QRS and associated repolarisation changes, benign T wave inversion in V3-V6 with J-waves and ST-elevation.
This ECG is from a man in his 40s who had an uncorrected Tetralogy of Fallot.
This ECG is from a man in his 40s who presented with chest discomfort and diaphoresis since waking a few hours earlier, on a background of prior infarction with PCI years ago, active smoking, high cholesterol and hypertension. This was the baseline ECG from 2 years prior.
This ECG is from a young woman who presented with status epilepticus seizures and an apparent overdose of bupropion, with possible cocaine ingestion. She was intubated and given propofol and benzodiazepines, which terminated the seizures. This was the repeat ECG 8 hours after presentation, just before she arrested.
This ECG is from a young woman who presented with status epilepticus seizures and an apparent overdose of bupropion, with possible cocaine ingestion. She was intubated and given propofol and benzodiazepines, which terminated the seizures, and then a PEA arrest was terminated with epinephrine and bicarbonate. This was the repeat ECG on day 4.
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?
