ECG of the Week 23rd November 2022 – Interpretation

Interpretation of ECG from 23 November 2022

The most obvious abnormality is ST segment elevation in leads I and aVL (maximally 2.5 – 3mm) as well as in leads V3 – V6. Additionally, there are deep Q waves in leads I and aVL, V5 and V6. There is poor R wave progression with R wave height in V3 < 3mm. There are reciprocal changes to ST segmental elevation in the form of ST segment depression in leads aVR, III and aVF.

The rhythm is sinus, the rate is approximately 100. P waves are normal and PR interval is not prolonged. There is corresponding biphasic T waves in the leads that show ST segmental elevation. The QT segment is not prolonged.
