ECG Cases 55 The Art of Occlusion MI Part 3 – Impression
In this ECG Cases blog Dr. Jesse McLaren guides us through 6 illustrative cases delving into overall impression in identifying occlusion MI. He discusses how using multiple OMI findings such as acute Q wave, subtle STE, reciprocal STD, hyperacute T waves, and reciprocal TWI to contribute to your overall impression, can double the sensitivity of STEMI criteria for acute coronary occlusion...

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...
