There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. PR depression, which suggests pericarditis 4.

We can see enough to make out that the rhythm is sinus tachycardia. Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW.

Here was the ECG: There is sinus tachycardia. Well, don't we see diffuse ST Elevation in Myo-pericarditis (with STD in aVR)? This was sent by a reader. A previously healthy 53 yo woman was transferred to a receiving hospital in cardiogenic shock. and K was normal. This is "Shark Fin" morphology. So this is STEMI, right? Which artery?

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.

I completely agree with Dr. Nossen that in this patient with new CP and sinus tachycardia with LAHB — that the T waves in each of the inferior leads are hyperacute ( ie, clearly disproportionately "bulky" given size of the QRS in these leads ). — and which other patient(s) need to be seen as soon as possible to figure out what is going on?

These latter findings are typical of pericarditis, but pericarditis never has reciprocal ST depression. Usually with pericarditis and myocarditis — hyperacute T waves (HATW) are not present. NOTE #1: Sinus tachycardia is not usually seen in an uncomplicated acute MI. This is OMI until proven otherwise.

You do NOT see this in normal variant STE, nor in pericarditis. In such cases, it is common for tachycardia to exaggerate the ST Elevation And, in fact, there was no new acute MI at this visit - troponins did not rise again. We have addressed this issue on many occasions in Dr. Smith’s ECG Blog.

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. Were they right?

I learned more about the history: 30-something African American with 5-7days of sharp R-sided shoulder/scapula/chest discomfort, presented with sinus tachycardia. There is also mild pericardial enhancement consistent with pericarditis. Definitive diagnosis is by MRI. OMI it is very unlikely with a week of constant pain.
