This ECG is from an elderly male who presented with chest pain. He has a pacemaker. This was his first prehospital ECG.
This ECG shows ventricular paced rhythm with concordant STE in aVR and concordant ST depression in II, III, aVF. The cause was most likely a proximal LAD or left main occlusion. This was missed and the patient died.
