Antero/inferior Infarction with left anterior hemiblock

Interpretation by Matthew Schumaecker
EKG edited and recorded by Dr. M. Rosengarten, MUHC, 1997

The rhythm is sinus rhythm at approximately 70/min. The deep S waves in the inferior leads and a left axis deviation indicates left anterior hemiblock.

There is poor R wave progression in the anterior precordial leads with a QS complex in V4. There is ST segment elevation in leads V1 to V4. There are very small or R waves leads II, III and aVF. All of these phenomena point towards the presence of an anterior wall and possible inferior wall infarction.
