ECG cases is a monthly blog by Jesse McLaren (@ECGcases), a Toronto emergency physician with an interest in emergency cardiology quality improvement and education. Each post features a number of ECGs related to a particular theme or diagnosis (with a focus on acute coronary occlusion), so you can test your interpretation skills. We challenge you with missed or delayed diagnosis, those with false positive diagnosis, and those that had a rapid and correct diagnosis. Cases are followed by a quick summary of the literature that relates to the cases, and we bring it home with practice changing pearls that you can use on your next shift.

ECG Cases 3: Can you find the subtle inferior MI?

In this ECG Cases blog we look at 8 patients with potentially ischemic symptoms, to highlight pearls and pitfalls of inferior MI. Can you identify which ones had acute coronary occlusion?...

In this ECG Cases blog we present ECGs from 7 patients who presented with chest pain and mild anterior ST elevation. Can you identify which were early repolarization and which were anterior STEMI?

ECG Cases 1: Missed Ischemia – Never Trust the ECG Computer Interpretation

In EM Cases' first ECG Cases blog we review 7 examples of ECGs of patients presenting to the ED with chest pain, who's ECG were read as normal by the computer. And guess what...they all show acute ischemia!
