What is Paroxysmal Atrial Fibrillation?
Paroxysmal Atrial Fibrillation: An Overview
Paroxysmal atrial fibrillation is a condition in which an irregular heart rhythm occurs periodically. The heart returns to its normal sinus rhythm on its own -- in a few minutes, hours, or days. People who have this type of atrial fibrillation may have episodes every day, or only a few times a year. When these episodes begin and end is usually unpredictable, which can be very unsettling.
About 1 in 4 people with paroxysmal atrial fibrillation eventually develop the permanent form of the condition.
Causes of Paroxysmal Atrial Fibrillation
The causes of paroxysmal atrial fibrillation aren't always known. They can be similar to causes of chronic atrial fibrillation, although most people with paroxysmal atrial fibrillation have normal hearts. Sick sinus syndrome is often found in people with paroxysmal atrial fibrillation.
Treating Paroxysmal Atrial Fibrillation and Related Complications
People with paroxysmal atrial fibrillation appear to be at just as high a risk of developing blood clots as those with chronic atrial fibrillation. However, the benefits of blood-thinning medications, such as
Coumadin®, have not been shown to be as effective as with chronic atrial fibrillation.
Your doctor considers a number of factors before recommending medication for paroxysmal
atrial fibrillation treatment. One consideration will be how often the paroxysmal atrial fibrillation episodes occur.
