Instructive ECGs in Emergency Medicine Clinical Context
Fantastic lecture. Thank you. Please record more.
Jim,Thanks! Please spread the word.You can see other lectures posted down the sidebar.Steve
thanks dr Smith, very interesting and practic information
Thanks for the feedback, Eduardo!
I think that QRS axis is +60 and T wave axis is -30 so the difference is 90 ( min 7:00 to 7:30) ? But what is normal range for Axis difference between QRS and T wave and its significance ?
Normal is not easily defined, but as the difference gets larger, the risk gets proportionally larger. > 100 definitely abnormal. My attention is caught if the angle is greater than 60 degrees, but this is not definitely abnormal.
But i know that If QRS-T angle >100 ,It's suspicious for secondary abnormality rather than primary as LVH ,and There is a big chance it’s not a STEMI ? So when to consider QRS/T angle abnormal if more than 100 ?
No good data. Large QRST angle does not imply STEMI. greater than 100 I would always consider abnormal. What it indicates depends on many factors.
I was waiting for this kind of lecture since long..THNX U sooo much...My question is in majority of females with or without chest pain we see so many repolarisation abnormalities so calles T wave changes..why so? It unnecessarily ends up investigating further including angio..as they complaints also some kind of non specific chest pain many times...Sir please opine..thanks once again
Only because the usual teaching is that T-wave inversion is ischemia and dangerous, when in fact most is benign. But it is not simple to tell the difference. Takes lots of study and experience.
