ABSTRACT:
A programmable pacing system and method, the system having the capability for providing an indication of recommended replacement time (RRT) as well as a prior warning of six months to RRT. RRT is determined by storing a value in the pacemaker corresponding to battery impedance at RRT, continuously periodically measuring battery impedance, and comparing the measured value with the stored RRT value. Whenever the pacemaker is reprogrammed to different operating conditions which affect RRT, or there is a significant change in load lead resistance, a new value of RRT impedance is calculated based upon a selected formula corresponding to the reprogrammed set of operating conditions, and stored in the pacemaker. At the same time, an Aging value of impedance is re-calculated to provide a six month warning before RRT, and likewise stored in the pacemaker.
