Posterior STEMI in early stages may have either inverted or upright T-waves. I have explained this complex idea in other posts. Later in posterior MI, they are upright.Steve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-82200482275304119352021-01-22T08:48:12.152-06:002021-01-22T08:48:12.152-06:00Sir,the true posterior mi will have st depression ...Sir,the true posterior mi will have st depression with upright t waves. Our first ecg doesn't have upright t wave. So how to explain this sir.

They call "lateral" posterior and that does not make sense. If the wall points to the posterior thorax where V7-V9 are or would be, I consider it posterior. If it points to the lateral thorax where V5 and V6 are, then I consider it lateral. The important thing is where the ischemia is in relation to the leads.Steve Smithhttps://www.blogger.com/profile/08027289511840815536noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-24005645253996657922020-12-24T07:21:55.370-06:002020-12-24T07:21:55.370-06:00Dr Smith,

Bayes de Luna referred to the infero-lateral wall as "posterior", yet from their image I don't think its vector can readily cause ST elevation in V7-9. Do you consider that region part of "posterior" wall as well or simply infero-lateral wall?<br /><br />Thanks.<br />JonathanAnonymoushttps://www.blogger.com/profile/05315671855718045013noreply@blogger.com
