She presented to the emergency department with a typical acute chest pain, almost 1 hour after symptom onset. An ECG was immediately obtained and revealed sinus bradycardia at 45 bpm, with 1–2 mm ST-depression at the J point that continued into a wide, tall, positive, symmetrical T-wave in leads V2–V6, and a 0.5 mm ST-elevation in lead aVR (figure 1A). She was immediately transferred to our primary coronary intervention (PCI) … ER -
