Prospective Physician-Initiated Observational Study of The Contact Detection System (CDS) in Patients Undergoing Radiofrequency Ablation Using the Niobe™ Remote Magnetic Navigation System

For all subjects included in the study, the ablation procedure will be started per standard of care. First mapping, pacing and electrocardiograms of the right atrium will be evaluated without the CDS box connected. Second the CDS box will be connected to the catheter and mapping, pacing and electrocardiograms will be recorded again. Next, ablation will be conducted per standard of care.
