Segments:
- Subtle ST depression in leads II, III, aVF

Interpretation:
- Concern was ACS with Wellen's pattern
What happened ? The patient was admitted under the cardiology team. She had a complicated in-patient stay due to several episodes of hematemesis secondary to a Mallory-Weiss tear. Her ECG during this time normalised with negative serial biomarkers, nil significant electrolyte abnormal, nil haemoglobin drop or period of cardiovascular instability. An echo and coronary angiogram were both normal. I'm at a loss to explain the dynamic ECG changes and wonder whether they represent a period of cardiac demand ischaemia / stress response or vasospasm.
