Lead monitoring frequency based on lead and patient characteristics
First Claim
1. An implantable medical device, comprising:
- an implantable medical device housing containing electronic circuitry;
an implantable lead electrically coupled to the housing;
an electrode positioned along the lead to sense a cardiac signal and to deliver cardiac therapy; and
a processor positioned within the housing and configured to determine the number of days the lead has been implanted prior to implanting of the medical device, perform a first update of a virtual lead days value associated with a number of days since implant of the lead in response to the determined number of days the lead has been implanted prior to implanting of the medical device, determine whether a lead condition is occurring in response to the sensed cardiac signal, and update a frequency of determining whether the lead condition is occurring in response to the determined first update of the virtual lead days value, wherein the processor is configured to perform the first update by increasing the virtual lead days value by the determined number of days the lead has been implanted prior to implanting of the medical device.

Abstract
A method and device for updating a frequency of determining whether a lead condition is occurring in a medical device that includes sensing a cardiac signal, determining the number of days the lead has been implanted prior to implanting of the medical device, performing a first update of a virtual lead days value associated with a number of days since implant of the lead in response to the determined number of days the lead has been implanted prior to implanting of the medical device, determining whether a lead condition is occurring in response to the sensed cardiac signal, and updating a frequency of determining whether the lead condition is occurring in response to the determined first update of the virtual lead days value.

19. A non-transitory computer readable medium storing a set of instructions which when implemented in a medical device cause the device to perform a method for updating a frequency of determining whether a lead condition is occurring, the method comprising:
-
sensing a cardiac signal; determining the number of days the lead has been implanted prior to implanting of the medical device; performing a first update of a virtual lead days value associated with a number of days since implant of the lead in response to the determined number of days the lead has been implanted prior to implanting of the medical device; determining whether a lead condition is occurring in response to the sensed cardiac signal; and updating a frequency of determining whether the lead condition is occurring in response to the determined first update of the virtual lead days value, wherein performing the first update comprises increasing the virtual lead days value by the determined number of days the lead has been implanted prior to implanting of the medical device.
