2. pericardial rub on auscultation
3. ECG
  1. -ST segment elevation -PR segment depression -T wave flattening and inversion
4. Chest X-ray
  1. Pleural effusion
5. CT Scan/ MRI
  1. Visualization of pericardium
6. Labs
  1. Markers for inflammation: -CRP -ESR -WBC
7. Echocardiogram
8. Pericardiocentisis
High risk Patients/ Medical History
1. -Fever (>38C) -Immunosuppression -Pulsus Paradoxus -Lyme Disease -Toxoplasmosis -Anticoagulant treatment
Complications
1. Recurrence of acute pericarditis
2. Pericardial effusion
3. Cardiac tamponade
4. Constructive pericarditis
Clinical Manifestations
