Is this inferor STEMI?

I received this ECG from a reader:

This is a very elderly female with chest discomfort and SOB.  Our interpretation was STEMI or demand ischemia.

Is there inferior STEMI?
Answer Below

The apparent ST elevation in II, III, and aVF is all due to the atrial flutter baseline causing PseudoSTEMI pattern.

There is no evidence of ischemia.
