Without follow-up on this case (and without awareness of cath findings) — I can NOT be certain — but my strong suspicion is that the ST-T waves in leads V2,V3 do NOT represent deWinter T waves because: <br /><br />i) The rhythm is Mobitz I — and Mobitz I is VERY common with acute inferior MI (and not nearly so common with anterior MI, as would be the infarct location if these were deWinter T waves); <br /><br />ii) The “shelf-like” ST depression that we see in lead V2 very much LOOKS LIKE what you see with acute posterior MI (ie, positive “Mirror Test”, as in my Figure-2) — whereas with deWinter T waves from anterior MI — there is typically a STEEP uprise from the J-point ST depression (and you do NOT see the “shelf”-like ST depression that we see here); <br /><br />iii) Lead V1 does not look like a recent anterior MI (especially given the relative amount of ST depression that we see in lead V2!) — whereas the ST-T wave picture in lead V1 could be perfectly consistent with recent infero-postero MI with RV involvement that is now showing “reperfusion T waves”; <br /><br />and, iv) I thought the limb lead changes (seen in 5 of the 6 limb leads) were much more consistent with recent Inferior MI, now with reperfusion T waves — and even if there was LAD occlusion with “wraparound” — I just wouldn’t expect the combined picture we see here in both limb and chest leads.ECG Interpretationhttps://www.blogger.com/profile/02309020028961384995noreply@blogger.comtag:blogger.com,1999:blog-3364570834099131201.post-14847365637905670352021-06-12T10:03:49.413-04:002021-06-12T10:03:49.413-04:00I thought the ST-T change in V2 V3 are definitely ...I thought the ST-T change in V2 V3 are definitely De-Winter T waves though. Is it possible that they are De-Winter T waves ?(though in the context of inferior wall MI, posterior involevment will be more common?)JJhttps://www.blogger.com/profile/17519255052010474217noreply@blogger.com
