(A) ECG of a 61‐year‐old female with severe chest pain. There is sinus tachycardia with ST elevation in aVR, ST depression in the inferior leads and mild upsloping ST depression in leads V₃–V₄ and tall T waves in V₁–V₃. Coronary angiography showed three vessel disease with total occlusion of the LAD. Left ventricular ejection fraction 20%. Patient underwent CABG. (B) Few days later, ECG shows QS wave in V₂ with mild ST elevation in V₂–V₅, compatible with recent anterior STEMI. (C) An ECG of a patient with acute myocardial infarction. There is upsloping ST depression with positive T waves in leads I, II, III, aVF, V₂–V₆. There is ST elevation in leads aVR and V₁.
