Edited by Bracey, Meyers, Grauer, and Smith A 50-something-year-old female with a history of an unknown personality disorder and alcohol use disorder arrived via EMS following cardiac arrest with return of spontaneous circulation. T wave alternans is a harbinger of cardiac instability and TdP. (3) No ischemic ST changes.

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. These are the conditions which have to be considered or excluded as they can sometimes manifest Brugada pattern on ECG.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

Smith: This bizarre ECG looks like a post cardiac arrest ECG with probable acidosis or hyperkalemia in addition to OMI. Bottom Line: Tests other than cardiac cath may be all that are needed to establish the diagnosis — but, I'd want to see a patient with this ECG as soon as would be possible. What was the pH and K?

The relationship between J wave and ventricular tachycardia during Takotsubo cardiomyopathy. Prominent J waves and ventricular fibrillation caused by myocarditis and pericarditis after BNT162b2 mRNA COVID-19 vaccination. The final letter in the SLOWED mnemonic is " D " for "Dead" ( resulting from VT/VF or asystolic cardiac arrest ).

Other than tachycardia, Other than slight tachycardia, vitals were within normal limits (including oxygen saturation). As always, takotsubo cardiomyopathy and focal pericarditis can mimic OMI, but takotsubo almost never mimics posterior MI, and both are diagnoses of exclusion after a negative cath. The PR interval is normal.
