The Magnetic Navigational Lab makes Providence one of the first providers in the United States for electrophysiology and in the world for interventional cardiology. This innovative diagnostic procedure represents the world's new standard of care in cardiovascular disease diagnosis and treatment. Twin computerize-controlled magnets, weighing more than two tons each, are moved into position in order to crate a magnetic field within the lab. Once in place, cardiologists use the system's computerized "joystick" device to reach areas in the heart that are simply impossible to reach with convention al procedures. Reaching theses areas in the cath lab setting will reduce the number of patients having to undergo more invasive procedures. This state-of-the-art equipment currently has two uses: coronary intervention applications which assist with structural problems of the heart such as blocked arteries and electrophysiology applications which precisely identify and isolate problems with the heart's rhythms.
