    摘要: A method includes selecting an electrode located in a patient; acquiring position information with respect to time for the electrode, during both acute and chronic states of the electrode, where the acquiring uses the electrode for repeatedly measuring electrical potentials in an electrical localization field established in the patient; calculating an acute state stability metric and a chronic state stability metric for the electrode based on the acquired position information with respect to time; and comparing the acute state stability metric to the chronic state stability metric to decide whether the electrode, as located in the patient in the chronic state, comprises a stable location for delivery of a therapy. The chronic state stability metric of an electrode may be monitored over time to decide whether stability of the electrode has changed.

    摘要: An exemplary method includes positioning a lead in a patient where the lead has a longitudinal axis that extends from a proximal end to a distal end and where the lead includes an electrode with an electrical center offset from the longitudinal axis of the lead body; measuring electrical potential in a three-dimensional potential field using the electrode; and based on the measuring and the offset of the electrical center, determining lead roll about the longitudinal axis of the lead body where lead roll may be used for correction of field heterogeneity, placement or navigation of the lead or physiological monitoring (e.g., cardiac function, respiration, etc.). Various other methods, devices, systems, etc., are also disclosed.
