摘要:
A system and method is provided that allows for determining the local impedance of one or more electrodes (20, 22a) of an electrode catheter (14). Such local impedance may be utilized to identify the relative position of an electrode catheter (14) to a sheath (18) of a guiding introducer. In another arrangement, local impedance of a catheter electrode can be utilized to calibrate a catheter electrode to provide improved contact sensing.
