If someone is having a heart attack. Would the pulse oximeter show an oxygen sat level below normal range?

In brief: Not necessarily

If the heart attack is huge, the heart will not pump effectively and blood will not circulate normally, causing a low oxygen saturation.
More commonly, the heart attack will be smaller and the heart will continue to pump effectively enough to get blood to the lungs and then to the body, keeping the oxygen saturation normal.
