2018 AFIB Ischemia 
Ken Grauer, MD
JANUARY 13, 2024
My written interpretation on a tracing such as this one would read, "Marked LVH and 'strain' and/or ischemia — with need for clinical correlation." BOTTOM LINE: ECG changes of LV "strain" and/or ischemia that we see on today's initial ECG — were not present 9 years earlier. WPW Cardiac arrhythmias ( including AFib ).

In some cases the ischemia can be seen "through" the flutter waves, whereas in other cases the arrhythmia must be terminated before the ischemia can be clearly distinguished. First , there can simply be diffuse ST depressions (which obligates reciprocal STE in aVR) associated with tachycardia which are not indicative of ischemia.

ACUTE MI (I allowed Acute MI to be in the report because I knew there would be an elevated troponin from ischemia, which is the definition of acute MI -- but in this case it would most likely be a Type 2 MI from tachycardia) There is also LA-RA lead reversal. The rhythm is rapid AFib. Atrial fib may cause Occlusion mimic."

. = My Comment by K EN G RAUER, MD ( 3/15 /2023 ): = I found today’s case highly instructive in highlighting a number of important aspects regarding the presentation and initial treatment of a patient who presents to the ED with new AFib. I focus my comment on a few additional aspects regarding new AFib.

When I was shown this ECG, I said it looks like such widespread ischemia that is might be a left main occlusion, or LM ischemia plus circumflex occlusion (high lateral and posterior OMI). There is STE in aVR. Thus, there is high lateral OMI with diffuse ST depression. Moreover, left main occlusion often presents near death.

The unique " shape " of the prominent ST-T wave abnormalities in this tracing — that are much more suggestive of some significant form of LVH ( L eft V entricular H ypertophy ) rather than ischemia. WPW Cardiac arrhythmias ( including AFib ). Voltage for LVH ( the R wave in lead aVL easily surpassing 12 mm ).

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). Chest trauma was suspected on initial exam. Here is his initial ECG around 1330: What do you think?
