pericardial friction rub
Grating sound heard on auscultation indicating pericardial inflammation.
pericardial tamponade
A life-threatening condition where fluid accumulation in the pericardium impairs cardiac filling and function.
pericardiotomy
Surgical incision of the pericardium to access the heart or relieve pericardial constriction during cardiac procedures.
