Atrial Fibrillation (AFib)

Atrial fibrillation is the most common type of arrhythmia (irregular heartbeat). Learn more about atrial fibrillation, and read about the care you can expect at Lehigh Valley Heart Institute’s Comprehensive Heart Rhythm Management Program.

With atrial fibrillation, the electrical signals in the atria (upper chambers of the heart) are fired in a very fast and uncontrolled manner. The chambers quiver instead of contracting normally.

About arrhythmia

When the atria do not contract effectively, blood may pool and/or clot. If a blood clot becomes lodged in an artery in the brain, a stroke (brain attack) may occur. About 15 percent of strokes occur in people with atrial fibrillation.

Treatment for arrhythmia

An arrhythmia is often controlled with medication. However, if you need a procedure to correct your irregular heartbeat, you will get the care you need at Lehigh Valley Heart Institute and the Comprehensive Heart Rhythm Management Program.

We offer a complete suite of medical, surgical and catheter-based treatments for heart rhythm problems, including: 

  • Ablations: Using the tip of a small catheter and heat (radiofrequency) or extreme cold (cryoablation), your cardiologist scars the heart tissue responsible for sending erratic electrical signals.
  • Maze procedures: Your doctor makes tiny incisions in a maze pattern on heart tissue. Scar tissue that forms around these incisions redirects the heart’s electrical signals.
  • Pacemakers: We offer Micra™, the world’s smallest, wire-free pacemaker, as well as MRI-compatible pacemakers. We’re also experts in cardiac resynchronization therapy (CRT) using biventricular pacemakers. This device keeps the right and left ventricles pumping together.
  • Implantable cardioverter defibrillators (ICD): ICDs work similar to pacemakers to restore a normal heartbeat. We offer a wireless subcutaneous (under-the-skin) ICD known as S-ICD.
  • WATCHMAN™ device: People who have arrhythmias are prone to developing blood clots in the heart’s left atrial appendage (LAA). WATCHMAN seals off the LAA, preventing clots from entering the bloodstream. This device reduces stroke risk and can be an alternative for patients who can’t take blood thinners.
  • Medication management: Some heart rhythm problems improve with medications that control heart rhythm or heart rate. You also may need blood thinners to lower stroke risk.

The Comprehensive Heart Rhythm Management Program offers ongoing care and monitoring for people with heart rhythm devices like pacemakers and implantable cardioverter defibrillators (ICDs).
