Normal
sac contains 50ml
Causes-
Infective pericarditis(Bacterial and viral)
TB
SLE/Rheumatoid arthritis
Post myocardial infarction/Dressler syndrome
Neoplasm
Trauma
Signs-(or temponade or
constrictive pericarditis)
Tachycardia (If low volume and pulsus paradoxus->Then it is tamponade)
Raised JVP(Kussmaul sign positive-Raised JVP during inspiration)
Low blood pressure
Impalpable apex
Cardiac dullness increased
Soft heart sound
Bronchial breath sound at inferior angle of scapula(Ewart sign-Due to compression of left lung base by heart)
Pericardial knock(3rd heart sound) , ascitis only in constrictive pericarditis

Pericardial knock(3rd heart sound) , ascitis only in constrictive pericarditis
Investigation-
CXR-PA view-Heart shadow enlarged , pear shaped and globular with oilgemic lung field
FBC-ESR rise in TB/SLE
ECG-Low voltage tracing and tachycardia
Echocardiogram-Echo free zone
Pericardiocentesis-Definitive investigation

Note:
Recurrent pericarditis-Malignancy ,uremia
Pericardial temponade-Compression of heart by rapidly developing pericardial effusion due to trauma ,mailgnancy ,dissecting aneurysm
Huge cardiomegaly-Pericardial effusion ,multiple
valvular disease ,dilated cardiomyopathy
Cardiogenic shock-Same features as other shock[Different shock is septic shock}
