The Cavanagh Difference

Cavanagh Heart Center takes a different approach to treating irregular heartbeats. Our electrophysiologists, doctors who specialize in irregular heartbeats, work with other doctors as well as nutritionists, rehabilitation experts, and other experts to make sure each patient receives the exact treatment they need.

Our electrophysiologists are all board certified and fellowship trained and train physicians from other parts of the country on new procedures.

Cavanagh Heart Center also provides patients access to clinical trials and the opportunity to try new treatments before they are widely available. Currently, Cavanagh Heart Center patients are participating in the Stop-AF Trial to test the effectiveness of cryoballoon ablation for irregular heartbeats.
