  2. Causes of increased pericardial fluid are: (4)
    • 1. Inflammation
    • 2. Pericarditis
    • 3. Rupture / tear in pericardial wall
    • 4. blunt trauma
  3. What's done when pericardiocentesis isn't successful?
  4. List some of the risks involved with pericardiocentesis: (4)
    • Cardiac arrest
    • arrhythmias
    • puncture heart wall
    • tear coronary arteries
  5. Define: myocardial biopsy
    Small piece of heart muscle is removed for pathological examination
  6. When is a myocardial biopsy warrented? (4)

  8. When do we use a pacemaker?
    When we have problems the the hearts electrical tissues
  9. What do we see on the echo of patient with a pacemaker?
    • M-Mode = motion of ventricle walls & septum
    • RV pace = early post IVS motion immediately post pacemaker

    Bottom line = we see wire in RV (nb to confirm it's pacemaker wire. Wire can cause veg or thrombus....check for)
  10. What is a pacemaker?
    A small electrical device that regulates heart - sends electrical signals to the heart
  11. Define: defibrillator (and who has one)?
    Pacemaker-like device; monitors heart; irregular rhythm and then shocks the heart. Afib patient.
