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.

Postablation chest pain consistent with pericarditis was reduced with colchicine (4% versus 15%; HR, 0.26 [95% CI, 0.09–0.77];P=0.02) This study aimed to evaluate a short-term anti-inflammatory treatment with colchicine following ablation of AF.METHODS:Patients scheduled for ablation were randomized to receive colchicine 0.6 2.02];P=0.89).

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.

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval. No ischemic ST changes.

That occurs in right heart failure and constrictive pericarditis. Constrictive pericarditis is an important cause for Kussmaul sign or inspiratory increase in jugular venous pressure. On the other hand, the Y descent is very prominent in constrictive pericarditis, and it is known as Friedreich’s sign.

MY Interpretation of Today's Initial ECG: I've labeled key findings in Figure-2 for today's initial ECG: The rhythm is sinus tachycardia at ~105/minute. The sinus tachycardia is a definite concern that something acute may be ongoing. Figure-2: I've labeled t he initial ECG. All intervals ( PR, QRS, QTc ) are normal.

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.

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.

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.

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?

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. There is upsloping ST elevation in III, with reciprocal ST depression in aVL.
