Answer to Question 1

The ventricles provide the pumping action that keeps blood moving. When the ventricles contract rapidly and uncontrollably (fibrillation), the force of the contractions is much less, sometimes drastically less. Without adequate pumping action, the heart effectively stops and hypoxemia ensues.

Answer to Question 2

paroxysm: sudden onset of a recurrent symptom
supraventricular: occurring at a point above the ventricles
tachycardia: a fast heart beat
Paroxysmal supraventricular tachycardia is a heart condition that causes the heart to beat too fast. The onset is sudden and the episodes tend to recur. The increased rhythm is caused by a lesion located in the upper portion of the heart (above the ventricles) that affects the electrical impulse of the heart.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
