The NOGA Cardiac Navigation System uses active magnetic fields generated from underneath the X-ray table in the Cardiac Cath lab along with a passive sensor from within the catheter tip to create three-dimensional cardiac maps. As the NOGA catheter is maneuvered within the left ventricle of the heart, its movement and location are tracked. The sensors provide data to a computer that calculates the precise location of the catheter tip relative to a fixed point on the patient. The computer than generates maps showing the electrical and mechanical characteristics of the inside surface of the heart. The NOGA system provides advanced diagnostic information regarding electromechanical function of the heart and assists your cardiologist in defining strategies to improve circulation.
