Here is an article I wrote: Updates on the ECG in ACS. Cardiac arrest can cause diffuse subendocardial ischemia, usually transient (it often resolves as time goes by after ROSC). STE limited to aVR is due to diffuse subendocardial ischemia, but what of STE in both aVR and V1? If you want to understand aVR, read this.]
