Pericardial Effusion presenting as Cough Syncope.

Syncope is a common clinical presentation and accounts for 1-3% of Emergency Department (ED) visits. Cough syncope is a rare type of situational syncope, often caused by respiratory conditions like bronchial asthma and chronic obstructive pulmonary disease. Cough syncope due to pericardial effusion is a rare but treatable condition. Delay in diagnosis can lead to fatal complications due to cardiac tamponade. We present a case of recurrent cough syncope caused by large pericardial effusion.
