afib clinic at boulder heart boulder community healthAtrial fibrillation (AFib) is an abnormal heart rhythm (arrhythmia) that impacts 1 in 5 individuals during their lifetime and accounts for 15-20% of strokes in the U.S. Fortunately, three out of four strokes caused by AFib can be prevented.

More than 50% of patients with AFib do not have obvious symptoms. Because AFib is a progressive disease, early diagnosis and careful management of the condition is crucial. An appointment with the AFib Clinic at Boulder Heart provides a centralized entry point into the only full-service cardiology program based in Boulder County, providing everything from diagnostic tests to advanced treatments to cardiopulmonary rehab.

“I asked around for the best doctors and facilities and ended up here at Boulder Community Health,” recalls AFib patient Matthew Gawin. “Best decision I could have made. My life is changed based on my experience with BCH.”
