This ECG is from a man in his 50s who presented with less than an hour of chest pain. This was his initial ECG.
This ECG shows subtle ST elevation in V2 and V3 with a very small amount of ST depression in V4-6. He was monitored and the ECG progressed into a clear STEMI. Catheterisation showed 95% proximal LAD stenosis and occluded 1st diagonal.
