This ECG is from a woman in her 70s who presented with central chest pain. This was the initial ECG.
This ECG shows ST elevation in V1-2 with ST depression in V4-6 as well as I, II and aVF. R wave progression is also poor. V1 is concerning for a hyperacute T wave. The chest pain worsened and the ECG changes evolved to meet STEMI criteria. Troponin was elevated. Catheterisation found a 100% proximal LAD occlusion.
