cardiac tamponade
see also:
introduction
- accumulation of pericardial fluid under pressure results in impaired cardiac venous filling and resultant impaired cardiac output which may rapidly become life threatening unless relieved by therapeutic pericardiocentesis
clinical features
- can be suspected based on:
- history and physical examination
- near-syncope or syncope
- hypotension
- tachycardia
- elevated JVP
- pulsus paradoxus
- peripheral oedema if subacute or chronic aetiology
- NB. must be differentiated from other conditions such as:
- constrictive pericarditis
- ECG:
- tachycardia
- low voltage
- electrical alternans
- CXR
- enlarged cardiac silhouette with clear lung fields
- echocardiogram
- chamber collapses
- abnormal venous flows
- exaggerated respiratory variation of cardiac and venous flows
- confirmed by the hemodynamic and clinical response to pericardial fluid drainage
