  1. Atrial Fibrillation - Topic Overview

    What is atrial fibrillation?Atrial fibrillation (say “A - tree - uhl fih - bruh - LAY - shun”) is an irregular heart rhythm (arrhythmia) that starts in the upper parts (atria) of the heart. Normally, the heart beats in a strong, steady rhythm. In atrial fibrillation, a problem with the heart’s electrical system causes the atria to quiver, or fibrillate. The quivering upsets the normal rhythm

  2. Atrial Fibrillation - Living With Atrial Fibrillation

    Since atrial fibrillation is often the result of an underlying heart condition, making changes to improve your heart condition will usually improve your overall health. Some of these changes include:Quitting smoking. Quitting smoking may be the most important step you can take to prevent coronary artery disease. For more information, see the topic Quitting Tobacco Use.Controlling your ...

  3. Pacemaker for Atrial Fibrillation

    A pacemaker is a battery - powered device about the size of a pocket watch that sends weak electrical impulses to “set a pace” so that the heart is able to maintain a regular heartbeat. There are two basic types of pacemakers:Single - chamber pacemakers stimulate one chamber of the heart, either an atrium or more often a ventricle. Dual - chamber pacemakers send electrical impulses to both the

  4. Electrical Cardioversion for Atrial Fibrillation

    Electrical cardioversion is a procedure in which an electric current is used to reset the heart's rhythm back to its regular pattern (normal sinus rhythm). The low - voltage electric current enters the body through metal paddles or patches applied to the chest wall. Cardioversion is used:To stop atrial fibrillation that has not stopped on its own or after a trial of antiarrhythmic medications has

  5. Atrial Fibrillation - Prevention

  7. Digoxin for Atrial Fibrillation

    Drug details for Digoxin for atrial fibrillation.

  8. Catheter Ablation for Atrial Fibrillation

    If medication is not effective or not tolerated for atrial fibrillation, a nonsurgical procedure called radiofrequency catheter ablation may be chosen. In this procedure thin, flexible wires are inserted into a vein in the groin and threaded up through the vein and into the heart. Through an electrode at the tip of the wires, radio waves can be delivered to selectively destroy heart tissue ...

    Drug details for Beta-blockers for atrial fibrillation.

  10. Atrial Fibrillation - Cause

    Atrial fibrillation is caused by a problem with the electrical activity of the heart.Conditions that damage the heart muscle or strain the heart often cause atrial fibrillation. These include:High blood pressure, a condition in which the force of blood against artery walls is too strong. Normal blood pressure is 119 millimeters of mercury (mm Hg) systolic over 79 mm Hg diastolic or below. ...
