Atrial Fibrillation

Atrial fibrillation (or flutter) is an irregular and fast heartbeat that prevents blood from flowing properly throughout the body.

The specialists in the CardioVascular Center at Tufts Medical Center in downtown Boston specialize in treating atrial fibrillation and other heart rhythm disorders. We provide a wide range of treatment options including medical therapy, ablation treatment, pacemakers and implantable cardiac defibrillators (ICDs).
