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 54 The Art of Occlusion MI: Scale and Proportionality
On this month's ECG Cases, Dr. Jesse McLaren explains how STEMI criteria can be false positive with large scale QRS and proportional ST elevation, or false negative with low/normal scale QRS and disproportionate ST elevation and hyperacute T waves, and that rules for subtle occlusion using proportionality can help differentiate LBBB with or without Occlusion MI, or LV aneurysm vs anterior STEMI with Q waves...
