Anterior Wall M.I.

Tue, 08/27/2013 - 15:03 -- Dawn

This series of three ECGs is from a 75-year-old woman who came to the Emergency Dept. with chest pain.  The first ECG shows ST elevation in V1, V2, and V3, with generally low voltage in the QRS complexes. There is some coving upward of the ST segment in aVR, which can suggest a very proximal lesion of the left coronary artery (LCA).  She was taken to the cath lab, where it was discovered that she had a 100% occlusion of the midportion of the anterior descending branch of the left coronary artery, which was repaired and stented.
