Always consider in patient with PEA
Always consider in patient with penetrating trauma anywhere in the cardiac box (80% result in<unk> 
Gun shot wounds are less likely to result in<unk>  because<unk>  defect is larger
Right ventricle is the most commonly injured chamber of the heart due to its anatomic location
Pathophysiology
Increased<unk>  pressure > decreased RV filling > decreased cardiac output
