Reality: Pericarditis causes localized ST elevations as well
Myth: only pericarditis causes defuse ST elevations
Reality: diffuse ST elevations can be see in STEMI as well
Myth: only pericarditis causes PR depressions

Myth: only pericarditis causes PR segment elevation in aVR.
Reality: PR segment elevation in aVR can be seen in STEMIs as well
Myth: pericarditis can be almost always be distinguished from STEMI on EKG
