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.
