In the last twenty years, radiofrequency ablation of cardiac arrhythmias has increasingly become the number one therapy as it is potentially curative and negates the need for long-term medication. Remote magnetic navigation is a proven technique used to reduce fluoroscopy and assist navigation to sites with difficult anatomic locations. The Niobe system (Stereotaxis, USA) used in those studies has two movable permanent magnets. In our electro-magnetic navigation system (eMNS), the movable permanent magnets are replaced with eight static electromagnets.
