Lead monitoring frequency based on lead and patient characteristics |
摘要 |
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 whether a lead condition is occurring in response to the sensed cardiac signal, determining whether a first patient characteristic is satisfied during a plurality of predetermined update periods, 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 first patient characteristic being satisfied, determining whether a patient characteristic update is satisfied in response to a second patient characteristic, different than the first patient characteristic, being satisfied, performing a second update of the virtual lead days value in response to the patient characteristic update being satisfied, and updating a frequency of determining whether the lead condition is occurring in response to the updated virtual lead days value. |

1. A medical device, comprising:
a device housing containing electronic circuitry; a 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 whether a lead condition is occurring in response to the sensed cardiac signal, determine whether a first patient characteristic is satisfied during a plurality of predetermined update periods, 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 first patient characteristic being satisfied, determine whether a patient characteristic update is satisfied in response to a second patient characteristic, different than the first patient characteristic, being satisfied, perform a second update of the virtual lead days value in response to the patient characteristic update being satisfied, and update a frequency of determining whether the lead condition is occurring in response to the updated virtual lead days value. |
