What EKG finding is typically associated with pericarditis?

• A. ST segment elevation with a peaked shape
• B. Flat or concave ST segment elevation
• C. Inverted T waves
• D. Q wave depression

Answer: (B)

The finding that is typically associated with pericarditis is characterized by flat or concave ST segment elevation. In pericarditis, the ST segment elevation is most often diffuse and occurs in multiple leads, rather than being localized to a specific area of the heart. The elevations are generally concave in shape and do not have the peaked appearance seen in other conditions such as acute myocardial infarction.

This pattern can be attributed to inflammation of the pericardial sac, which affects the electrical conduction system of the heart, causing the characteristic changes seen on an EKG. Importantly, the concave shape of the ST segments is a notable feature that helps differentiate pericarditis from other conditions that may present with ST segment changes. It is crucial for clinicians to recognize this finding, as it aids in the diagnosis of pericarditis and distinguishes it from more serious conditions that may present similarly.
