She presented to an outside hospital after several days of malaise and feeling unwell. This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). Electrocardiographic diagnosis of postinfarction regional pericarditis Oliva PB.

This rules out pericarditis, which essentially never has reciprocal ST depression. When flow is restored, wall motion may completely recover so that echocardiogram does not detect the previous ischemia. This is not pericarditis because: a. Pericarditis does not have reciprocal depression.

In any case, the ECG is diagnostic of severe ischemia and probably OMI. These latter findings are typical of pericarditis, but pericarditis never has reciprocal ST depression. Nossen Comment/Interpretation: Evaluation of ischemia on an ECG can be very challenging. Concordant STE of 1 mm in just one lead or 2a.

He was seen at another hospital and found to have a slightly elevated troponin, then underwent a CT pulmonary angiogram (PE) protocol which revealed a right sided pneumonia. Echo does not necessarily differentiate acute MI from pericarditis: both may have wall motion abnormalities. See an examples of CT ischemia here.

A previously healthy 53 yo woman was transferred to a receiving hospital in cardiogenic shock. Well, don't we see diffuse ST Elevation in Myo-pericarditis (with STD in aVR)? Our chief of cardiology, Gautam Shroff, interprets it differently and thinks this is indeed ischemia. This was sent by a reader. and K was normal.

The differential is: Posterolateral OMI or subendocardial ischemia The distinction between posterior OMI and subendocardial ischemia can be important and sometimes difficult. Ischemic ST depression includes posterior OMI and subendocardial ischemia. Her prior ECG on file is shown below: What are your next steps?
