In my opinion (as I detail above) — YES, the T waves especially in V2 and V3 of ECG #1 (possibly also in V4, though I intentionally chose not to mention that) ARE hyperacute. PLEASE take a look at My Comment above — and let me know after reading it if you still have this question. (NOTE: Since I never know when Steve or Pendell will be publishing a case — there OFTEN is a slight lag time until I am able to write My Comment ... — :)ECG Interpretationhttps://www.blogger.com/profile/02309020028961384995noreply@blogger.comtag:blogger.com,1999:blog-549949223388475481.post-64209176619405436602019-09-28T20:56:09.747-05:002019-09-28T20:56:09.747-05:00@ Jody — YES, your system works.

Then the NEXT thing I do, is to look at the “a” ( = augmented) leads — and you’ll note that the greatest amplitude of artifact in the 3 “a” leads in ECG #1 is aVF — which CONFIRMS the left Foot as the “culprit” extremity. As in the short article by Rowlands that I’ve reproduced in Figs 2,3,4 — formulas are given, which further confirm the left Foot — because ~1/2 the amplitude of the artifact is seen in the other 2 “a” leads.
