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.

His response: “subendocardial ischemia. Smith : It should be noted that, in subendocardial ischemia, in contrast to OMI, absence of wall motion abnormality is common. With the history of Afib, CTA abdomen was ordered to r/o mesenteric ischemia vs ischemic colitis vs small bowel obstruction. Anything more on history?

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?
