  1. Pericardial Effusion
    • the escape of blood or other fluid into the pericardium.
    • 1. Pericarditis
    • 2. Congestive heart failure
  2. Pericarditis & Congestive cardiac failure
    • 1. Inflammation of pericardium -> fluid accummuate in pericardial cavity -> severe chest pain
    • 2. Inability to maintain blood circulation. The heart has lost the ability to pump enough blood to the body's tissues.
    • With too little blood being delivered, the organs and other tissues do not receive enough oxygen and nutrients to function properly.
  3. Cardiac Tamponade
    • Blood in the pericardial cavity
    • Cause: Stab wound; Myocardial infarction (rupture of heart muscle)
    • Treatment: pericardio-centesis (remove fluid using needle)
  4. Beck's Traid
    • Three medical signs: associated with acute cardiac tamponade, fluid
    • accumulates around the heart and impairs its ability to pump blood.
    • Result is Triad:
    • Low blood pressure (heart can't pump out enough blood to body)
    • Muffled cardiac sound (quiet sound of heart)
    • Distended neck vein or increased central venous pressure (back-up of blood in vein because blood stuck in the heart)
