Definition of Cardiac tamponade
Cardiac tamponade: A life-threatening situation in which there is such
a large amount of blood or other fluid inside the pericardial sac around the
heart that it interferes with the performance of the heart. If cardiac tamponade
is left untreated, the result is dangerously low blood pressure, shock, and
death. The excess fluid in the pericardial sac acts to compress and constrict
the heart and severely restrict its function. Cardiac tamponade can be due to
excessive pericardial fluid, a wound to the heart, or rupture of the heart. Also
known as pericardial tamponade.
