An ECG sent to me with concern for hyperacute T-waves

This ECG is from a woman in her 70s who presented with sudden nausea, diaphoresis and brief syncope.

This ECG shows subtle concave ST elevation in inferior leads and V4-6. The angiogram was normal, troponins negative and echo showed no wall motion abnormality. The most likely cause was a normal variant.

Large T-waves and a Computer Interpretation of ***Acute MI***

This ECG is from a man who presented with a malfunctioning ICD but no chest pain or dyspnoea.

This ECG shows large T waves out of proportion to the QRS but with a very concave upstroke. This was similar to the baseline ECG. There was no acute infarction.
