Atrial fibrillation occurs if the atria contracts at a high rate and in an irregular manner. The human heart is comprised of 2 upper chambers and 2 lower chambers. The upper chambers are called the atria – left and right atria while the 2 lower chambers are the left and right ventricle.

Some individuals with atrial fibrillation do not have any indications. The condition is only detected during a routine medical exam or after a health issue.
Management of atrial fibrillation
There are various treatment options for atrial fibrillation. The treatment largely depends on the exact cause of the condition.
Oftentimes, all that is required is to manage the cause such as in cases involving an overactive thyroid gland. In some cases, there is no underlying cause and the doctor must try out various treatment options before finding the right one for the individual.
It is important to note that controlling atrial fibrillation can be approached in 2 manners – restoring the normal heart rhythm and controlling the rate of the heart beats. The medications that are used work by restoring the normal heart rhythm and controlling the heart rate.
In some cases, the individual might be required to use more than one anti-arrhythmic medication. A beta-blocker might be prescribed by the doctor to restore the normal heart rhythm. When controlling the rate of the heartbeat, the objective is to lower the heart rate below 90 beats per minute. The doctor might initially use a beta-blocker first or a channel blocker. One of these medications can be given along with digoxin or amiodarone to further regulate the heart rate.
