This case report is kindly provided by Michael Rosengarten from McGill and is part of the McGill Cases. These cases come from the McGill EKG World Encyclopedia.
This EKG shows sinus rhythm. The QRS shows q waves in the inferior leads which are wide (>30ms) and about 25% of the QRS height in aVF. There is also slight ST ellivation in the inferior leads and T wave inversion. The EKG suggests an inferior wall infarction, probably old. (the best way to determine "old" is to see a previous cardiogram).
