What does this ECG show?
This is how every question works. Read the tracing, commit to an answer, then see the findings marked on the ECG.
A 67-year-old woman has had 40 minutes of heavy central chest pressure with nausea and sweating.
What is the most likely diagnosis?
ST elevation in II, III and aVF, with mirror-image ST depression in I and aVL, in a patient with ongoing pain. This is an acute inferior STEMI: activate the cath lab.
How it works
Practice the way you read on the ward.
Do a structured read
Rate, rhythm, axis, intervals and key findings, every time. It is the habit that stops you missing things.
Measure with calipers
Drag calipers across the tracing to time the PR, QRS and QT, just like on paper.
Commit to an answer
Pick the diagnosis and next step, and say how sure you are. Confident mistakes are the ones worth learning from.
See exactly where to look
Every answer marks the findings on the ECG and compares your read with the expert read, line by line.

The beta is free. After launch there will be a yearly plan. The first 100 people on the waitlist get 50% off their first year, and you don't pay anything to claim a spot.
Are the ECGs real?expand_more
Yes. They are real 12-lead recordings from open research datasets, used under their licences, and every case is checked by a cardiologist.
Does it work on my phone?expand_more
Yes. It works in any browser on phone, tablet or laptop, with a lead switcher for small screens.
What topics are covered?expand_more
