Atrial fibrillation or afib is the most common type of irregular heart rhythm, with 2.7 million Americans living with the condition. Afib occurs when the upper chambers of the heart beat irregularly and cause the lower chambers of the heart to pump blood abnormally and ineffectively throughout the body.

Over time, afib may become more frequent and longer lasting, sometimes leading to permanent or chronic afib. All types of afib can increase your risk of stroke. Even if you have no symptoms at all, you are nearly five times more likely to have a stroke than someone who doesn’t have atrial fibrillation.

Our treatment options for atrial fibrillation include:

  • Medications
  • Cardioversion
  • Catheter ablation
  • Radio frequency ablation
  • Cryoablation
  • HYBRID MAZE: includes surgical and catheter ablation
  • Watchman™


Memorial Hospital is proud to be the first hospital in northeast Florida to offer the Watchman™ device, a new stroke risk reduction option and an alternative to long-term warfarin therapy for patients with atrial fibrillation.

The Watchman™ device is implanted through the leg using a catheter-based system. The device is designed to permanently close off the left atrial appendage, believed to be the source of a majority of stroke-causing blood clots.

Implanting the Watchman™ device is a one-time procedure that usually lasts about an hour and is typically conducted with general anesthesia. Following the procedure, patients typically stay in the hospital 24 hours and, over time, some can discontinue long-term warfarin therapy.
