Electrocardiography

 * Characteristic ST elevations with PR depression may be noted in all leads in presence of pericarditis.
 * In case of pericardial effusion or cardiac tamponade, micro-voltage with electical alternans may be observed which could be due to swinging motion of heart in pool of pericardial fluid.
 * Constrictive pericarditis may present with ECG changes consistent with atrial fibrillation.
