A middle-aged man called EMS for chest pain.
This prehospital ECG was recorded:
 |
| Obvious Anterior STEMI due to proximal LAD occlusion (with STE in aVL and reciprocal STD in inferior leads). |
On arrival to the ED, this ECG was recorded 10 minutes later:
 |
| Almost all STE is gone, but the hyperacute T-waves remain |
While waiting for the cath team, this was recorded 30 minutes after 2nd ECG:
 |
| Now there are classic de Winter's T-waves. |
The patient was found to have a 100% proximal LAD occlusion.
By the time of the angiogram, which is never at the same the time as the ECG, there was not even a trickle of blood.
See this related post, with discussion of de Winter's T-waves:
Exceptional (STE, only T-wave, de Winter)
ReplyDeleteBetween 2.ECG (hyperacute T-wave AFTER STE) and 3.ECG (de Winter)
it's possible to establish which of the two is "more occluded"
(or "more reperfused") ?
Thanks - Al
I believe that it is more open with the deWinter's, but this is because it is all in transition. A completely occluded artery can have hyperacute T-waves without any ST shift (STD or STE) because the ST has not YET shifted. In this case, I think the artery opened just a trickle and the ST was shifting from STE to STD but had not YET become depressed.
