Mid-anterior MI

A Mid-anterior MI causes ST elevation in aVL and V2. It occurs when there is an occlusion of a first diagonal branch of the LAD artery.

The delay between OMI and STEMI claims yet another patient’s anterior wall

This ECG is from an elderly woman who presented with chest pain and shortness of breath.

This ECG shows ST elevation in V2 with hyperacute T waves in V2-3. Even though this does not meet STEMI criteria, it is highly suspicious. Serial troponins did rise, pain was ongoing and the ECG evolved to meet STEMI criteria. A 100% mid-LAD occlusion was found to be the cause. Echo showed widespread wall motion abnormalities and reduced ejection fraction.
