Several conditions, including life threatening conditions such as myocardial infarction, aortic dissection and pulmonary embolism produce signs and symptoms that are similar to those produced by pericarditis.

Pain along the trapezius ridge(s), is very characteristic of pericarditis. The pain of myocardial infarction tends to involve the anterior precordium with radiation to the left arm.
Unlike cardiac ischemia, the pain of pericarditis often lasts longer, is sharper and unresponsive to vasodilator therapy.
The EKG of pericarditis shows PR segment depression while the EKG of myocardial infarction does not.
The EKG of pericarditis shows ST elevation that does not necessarily follow the anatomic distribution of a single coronary artery.

-Keep in mind that pericarditis might also be one of the following: part of a generalized disease, an isolated disease, part of a disease that affects a nearby organ, and sometimes is the presenting syndrome of multiple diseases.
