Pericardial Tamponade
Pericardial tamponade is an abnormal accumulation of fluid in the pericardial space which results in diminshed filling of the atria and subsequently the ventricles complicated by reduction in cardiac output.
Th rapidity with which fluid accumulateds is a major factor in the development of tamponade. Since blood usually accumulates rapidly hemorrhage into the pericardium is a common cause of tampnade. Penetrating trauma and hemorrhagig malignant effusions are therefore the common causes of tamponade.
