Abstract

A method and system include a processor that outputs a model of anatomical structures of a region in which a leadwire is implanted, the structures being distinguished by graphical indicia associated with respective textual descriptions in a legend. Electrodes of a model of the leadwire overlaid on the anatomical structure models are selectable, in response to which selection the processor displays a control for modifying an electrical setting of the selected contact.
