Definitive treatment of a pericardial tamponade is

Pericardial tamponade causes a dangerous drop in cardiac output because the heart is mechanically compressed by fluid in the pericardial sac, limiting filling during diastole. The definitive treatment is to relieve that pressure by draining the fluid. Pericardiocentesis, the procedure to aspirate the pericardial fluid, directly removes the cause of the compression and restores normal filling and circulation. In some cases—especially certain traumas or recurrent tamponade—definitive surgical drainage (like a pericardial window or, if needed, thoracotomy) may be performed, but the immediate, life-saving move is draining the pericardial space. Defibrillation addresses a heart rhythm problem, not the mechanical compression. Thrombolysis targets clots, not fluid in the pericardial sac. Thoracotomy can be necessary in specific traumatic scenarios, but it is not the standard definitive treatment for tamponade in general.
