What is Atrial Fibrillation (AF)?
Atrial fibrillation (AF) is the most commonly diagnosed arrhythmia,
which is characterized by fast and irregular heart rhythms. It is caused by electrical abnormalities located in the pulmonary veins of the left atrium.
Device Therapy for AF
In a subset of patients with paroxysmal (intermittent) or persistent atrial fibrillation, devices can be used to either prevent atrial fibrillation or convert it to a normal sinus rhythm. These devices include pacemakers and implantable cardioverter defibrillators (ICD).
(For more information, see
see Pacemaker Implantation
or
ICD Insertion.)
Types of Devices Most Commonly Used:
Some of the newer and more commonly used devices include:
St. Jude IdenityŽ XLDR Pacemaker
A clinical study of the IdenityŽ XLDR Pacemaker showed that its specific pacing algorithm decreased episodes of atrial fibrillation.

Medtronic GEM IIIŽ AT ICD
The GEMŽ III AT ICD is an implantable defibrillator that not only treats life threatening arrhythmia, but can convert atrial fibrillation back to a normal rhythm. If atrial fibrillation occurs, it delivers electrical therapy that restores the heart back to a normal rhythm. It is the only device approved for use in atrial fibrillation.
