Electrocardiogram (ECG) changes in acute pericarditis mainly indicates inflammation of the epicardium (the layer directly surrounding the heart), since the fibrous pericardium is electrically inert. For example, in uremia, there is no inflammation in the epicardium, only fibrin deposition, and therefore the EKG in uremic pericarditis will be ...
The onset of purulent pericarditis is usually acute, with most individuals presenting to a medical facility approximately 3 days following the onset of symptoms. [4] As a subtype of pericarditis, purulent pericarditis often presents with substernal chest pain that is exacerbated by deep breathing and lying in the supine position. [5]
Depending on the time of presentation and duration, pericarditis is divided into "acute" and "chronic" forms. Acute pericarditis is more common than chronic pericarditis, and can occur as a complication of infections, immunologic conditions, or even as a result of a heart attack (myocardial infarction), as Dressler's syndrome.
Myocardial infarction (see also ECG in myocardial infarction). ST elevation in select leads is more common with myocardial infarction. ST elevation only occurs in full thickness infarction; Prinzmetal's angina [5] Acute pericarditis [6] [7] ST elevation in all leads (diffuse ST elevation) is more common with acute pericarditis. Left ventricular ...

Uremic pericarditis is associated with azotemia, and occurs in about 6-10% of kidney failure patients. BUN is normally >60 mg/dL (normal is 7–20 mg/dL). However, the degree of pericarditis does not correlate with the degree of serum BUN or creatinine elevation. The pathogenesis is poorly understood. [2]
Patients who present with dyspnea or chest pain have a broad differential diagnosis and it may be necessary to rule out other causes like myocardial infarction, pulmonary embolism, pneumothorax, acute pericarditis, pneumonia, and esophageal rupture. [2] Initial tests include electrocardiography (ECG) and chest x-ray.
Dressler syndrome is also known as postmyocardial infarction syndrome [1] and the term is sometimes used to refer to post-pericardiotomy pericarditis. It was first characterized by William Dressler at Maimonides Medical Center in 1956.
