Hmm... ST depression often means there is ST elevation somehwere you can't see. ST depression is generally a 'reciprocal' change, and there will be elevation on the opposite side of the heart.
A 'standard' EKG looks at the front, bottom, and left side of the heart. If the area of the heart affected by the heart attack is on the right or back side, then you won't see elevation, but you may see the reciprocal depression.
EDIT: s/almost certainly/often/
- Herodotus38 11y agoI wouldn't say certainly, but sometimes. There are a lot of more common causes of ST depressions than STEMIs. For example, left ventricular hypertrophy with tachycardia.
- JshWright 11y agoFair point. I meant that if you see ST depression in an MI, then it's probably not _actually_ an NSTEMI, you just probably don't have the leads you need.
