'''Cardiac tamponade''' is a condition where a [[pericardial effusion]] compresses the heart, leading to life-threatening [[acute heart failure]]. This occurs if the pericardial effusion develops rapidly or is large. It’s an emergency which should be treated empirically even before a proper diagnosis is made.

== Etiology ==
 
* Acute [[pericarditis]]
* Cardiac wall rupture (trauma, [[Acute myocardial infarction|MI]])
* Cardiac surgery
 
== Clinical features ==
Cardiac tamponade has a distinct clinical presentation:
 
* [[Hypotension]]
* Tachycardia
* Jugular venous congestion
* <abbr>[[Pulsus paradoxus]]</abbr>
 
== Diagnosis and evaluation ==
 
* [[Electrocardiography|ECG]] – low voltage, electrical alternans
* [[Chest x-ray|X-ray]] – enlarged cardiac silhouette
* [[Echocardiography]] – large effusion, collapse of chambers, swinging of the heart
 
== Treatment ==
Treatment should not be delayed due to diagnostic evaluations. Treatment is by pericardiocentesis, under [[ultrasound]] or [[Fluoroscopy|fluoroscopic]] guidance. If unsuccessful, surgery may be necessary.
