Abstract: An impedance location of an electrode in an impedance based coordinate system and a magnetic location of a magnetic position sensor in a magnetic based coordinate system can be received. A transformed impedance location of the magnetic position sensor can be computed. A difference between the transformed impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be determined. A magnitude of the difference between the impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be computed. A statistical significance of the difference between the transformed impedance location of the magnetic position sensor and the magnetic location of the magnetic position sensor can be computed. A determination can be made that an impedance shift exists if the magnitude of the difference exceeds a threshold and a statistical significance of the difference exceeds a threshold.

Abstract: A location of a number of fiducial points can be computed. The fiducial points can include impedance locations of an electrode disposed on a catheter in an impedance based coordinate system and magnetic locations of a magnetic position sensor disposed on the catheter in a magnetic based coordinate system. The impedance location of the electrode in the impedance based coordinate system can be transformed into a transformed impedance location of the electrode in the magnetic based coordinate system. A magnetic location of the electrode in the magnetic based coordinate system can be determined. A determination of whether an impedance shift exists between the transformed impedance location of the electrode in the magnetic based system and the magnetic location of the electrode in the magnetic based system can be made. An electromagnetic dynamic registration can be generated between the impedance based coordinate system and the magnetic based coordinate system based on the impedance shift.
