The evaluation of pericarditis begins with a history and physical exam.

Physical findings in someone with pericarditis may include:

• Pericardial friction rub:
• An abnormal sound caused by the heart rubbing against the pericardium
• Heard during examination with a stethoscope
• Rapid pulse:
• Greater than 120 beats per minute
• Rapid breathing rate
• Leg swelling (bilateral)

Tests are necessary to make the diagnosis of pericarditis.

Tests that may be used to evaluate pericarditis include:

• Cardiac enzymes
• Complete blood count
• Erythrocyte sedimentation rate
• Electrocardiogram
• Chest x-ray
• Echocardiogram
• Viral cultures of the pericardium
• Viral antibody tests
