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) Rate (/min) 53 QT (ms) 422
pr (ms) 171 QRS axis (degrees) 60
QRS (ms) 102
