Abstract:
1. A method for obtaining motion data for a physiological location of a body, the method comprising: producing an electric field from a pair of broadcasting electrodes in a first satellite structure formed on a pacing lead, wherein the pacing lead is implanted in a body; detecting a change in an electric potential of a receiving electrode in a second satellite structure formed on the pacing lead in response to a movement of the pacing lead, wherein the electric potential of the receiving electrode is induced by the electric field, and wherein the receiving electrode is attached to a physiological location of the body; determining an angle by which the receiving electrode deflects from a mid-potential plane between the pair of broadcasting electrodes by processing the change in the electric potential of the receiving electrode; and generating motion data for the physiological location of the body based on the angle by which the receiving electrode deflects from the mid-potential plane.
