AFIB Arrhythmia Ischemia

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. In this case, there is diffuse ischemic ST depression of subendocardial ischemia, of course with accompanying reciprocal STE in aVR.

. = 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.

M y I MPRESSION : The rhythm in Figure -1 is almost certain to be very rapid AFib in a patient with WPW. NOTE #2: Surprisingly, it is not uncommon for patients in AFib with WPW to be hemodynamically stable — despite having exceedingly rapid ventricular rates. The resultant rhythm after cardioversion is shown in Figure-2.

Osborn waves have been reported with hypercalcemia, brain injury, subarachnoid hemorrhage, Brugada syndrome, cardiac arrest from VFib — and — severe, acute ischemia resulting in acute MI ( See My Comment in the November 22, 2019 post on Dr. Smith’s Blog ). Rituparna et al — as well as Chauhan and Brahma ( Int.

These findings suggest that instead of VT — the rhythm in Figure-1 is AFib with a fairly rapid ventricular response. Since the rhythm is supraventricular (ie, AFib ) — we can accurately assess QRS morphology. Shark Fin" ST segment elevation is most often a sign of severe transmural ischemia that results from acute coronary occlusion.

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 ).

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). The "usual rules" of cardiac arrhythmias are simply not always followed in critically ill patients. There is STE in aVR.
