Dr. Noonan: Redefining Cardiac Mapping and Ablation

Dr. Daniel Noonan discusses how RHYTHMIA HDx has changed the cardiac mapping space and his practice at St. Luke's Boise Medical Center. He shares how RHYTHMIA HDx high-definition mapping system and features have improved his workflow, his approach to complex cases and his patients.

Dr. Della Bella: RHYTHMIA HDx Mapping System

Dr. Paolo Della Bella discusses the advantages offered by the RHYTHMIA HDx Mapping System and explains the clinical value offered by the system's unique combination of greater density, higher resolution and rapid automation.

Dr. Mounsey: How RHYTHMIA HDx Has Set a New Standard in 3D Mapping

Dr. Paul Mounsey of UNC Center for Heart and Vascular Care describes how the RHYTHMIA HDx  Mapping System has “set a new standard” in 3D mapping. This five-minute clip details the key features of the system he and his team have been using since the system was installed.

Dr. Yang: Unparalleled Clarity in Cardiac Mapping Video

Listen to Dr. Felix Yang from Maimonides Medical Center in New York City talk about how RHYTHMIA HDx has surpassed the clarity of other cardiac mapping and navigation systems. “Whereas frequently we only have a rough idea of how an arrhythmia would propagate and we may deliver empiric ablation lines to treat them, the high-definition maps acquired by the system allow us to actually see what are the critical components of an arrhythmia circuit.”
