The Duke Heart Rhythm Service at Duke University Hospital is the first electrophysiology center in the Triangle to offer a new, specialized treatment for chronic atria fibrillation.

It’s called pulmonary vein isolation or catheter ablation treatment for atria fibrillation, and it combines medications with an intensive ablation procedure that uses microwave energy to repair problems in the heart tissue.

“It is a very exciting way to help people with rhythm problems that have not responded well to medications,” says Greenfield. “Our physicians and nurse practitioners specialize in atria fibrillation, so we can bring a very focused, whole-person approach to the problem and help people who haven’t been able to find relief.”

Does your heart go pitter, or pat?

Symptoms of heart rhythm problems include:

• Fatigue
• Exercise intolerance
• Weakness
• Dizziness
• Fainting
• Heartbeats that skip and race

Your primary-care doctor can identify a rhythm problem and refer you to a specialist for further care.
