This ECG is from a woman in her 70s who was awoken with sharp chest pain on a background of cardiomyopathy, ICD and LVH.
This ECG shows paced rhythm with modified-Sgarbossa positive discordant ST elevation in I, aVL and V2. Angiogram did not find a culprit and echo did not find a wall motion abnormality. The cause remains a mystery.
