Ok. So I am gonna pull the "I'm still a bit of a newbie" card. I know what a STEMI is... what is looks like, get them to cath lab right away. But what in the world is a Non Q Wave MI? I've never seen anything change on an EKG with a Q wave that I know. What does it (the Q wave) look like in one of these?
There are 2 types of acute MI--transmural and non-transmural. A transmural MI involves the full thickness of the wall of the ventricle--shown as a STEMI on the EKG. A non-transmural MI, or non-Q wave MI, involves only partial thickness of the wall and can be diagnosed with cardiac enzymes. Changes in the EKG won't be evident until the MI evolves, i.e. flipped T waves. If the first set of enzymes is positive the patient may win a trip to the Cath Lab so that potential problems can be averted. If there's one artery blocked there may be others waiting in the wings.
