Method and apparatus for dynamically monitoring, detecting and diagnosing lead conditions

An apparatus for detecting a lead-related condition, comprising:

• means for collecting a first set of data of a plurality of medical electrical lead surveillance parameters from an active implantable medical device (IMD) implanted in a subject;
• means for concurrently comparing the collected plurality of lead surveillance parameters to a baseline template to evaluate any deviation, wherein the baseline template is a digitized representation of data patterns or sequences of lead-related data, wherein said baseline template includes a similar plurality of medical electrical lead surveillance parameters from the active IMD implanted in the subject;
• and
• means for determining whether the deviation is indicative of lead failure.

A method for detecting a lead related condition comprising:

• defining a plurality of medical electrical lead surveillance parameters;
• defining a first sampling rate for each of the plurality of surveillance parameters, wherein each of the sampling rates is independent of the other sampling rates;
• creating a patient specific baseline template, wherein the baseline template is a digitized representation of data patterns or sequences of lead-related data, wherein the method of creating the template comprises:
• collecting a first set of data of the plurality of surveillance parameters at the defined sampling rates;
• and
• generating a patient specific template based on the first set of data;
• diagnosing the lead related condition, wherein the method of diagnosing comprises:
• collecting a second set of data of the plurality of surveillance parameters at the defined sampling rates;
• and concurrently comparing the second set of data to the baseline template to evaluate any deviation;
• and
• determining whether the deviation is indicative of lead failure.
