atrial fibrillation

Atrial fibrillation is the most common type of arrhythmia and occurs when rapid disorganized electrical signals in the heart's upper 2 chambers (atria) causes them to contract very fast and irregularly.  This causes blood to pool in the atria and it is not pumped completely into the heart's 2 lower chambers (ventricles).  The upper and lower chambers of the heart do not work together as they should.


Symptoms may include:


Causes may include:


Treatment may include: 

  • medication
  • electrical cardioversion - a jolt of electricity is delivered to the heart in an attempt to restore normal heart rhythm
  • ablation - used to restore a normal heart rhythm when medicines or electrical cardioversion does not work
