Patent ID: 7797047

Claim:
A method of lead status monitoring by a lead status monitor in an implantable medical device, the method comprising: measuring an impedance along an electrical pathway; measuring a non-physiologic sensed event along the electrical pathway; collecting data relating to a percent of time in mode switch, an R-wave amplitude, a P-wave amplitude, a reversion pace count, and a time from implant; processing, by the lead status monitor, the collected data, the measured impedance and the non-physiologic sensed events with an algorithm having a set of weighted sum rules, and determine a result of the algorithm, wherein the algorithm assigns a weight to each of the measured impedance, the measured non-physiologic sensed event, and each of the percent of time in mode switch, the R-wave amplitude, the P-wave amplitude, the reversion pace count, and the time from implant; and determining, by the lead status monitor, if a lead status event has occurred based on the result of the algorithm.
