Abstract
Techniques for performing lead functionality tests, e.g., lead impedance tests, for implantable electrical leads are described. In some of the described embodiments, an implantable medical device determines whether a patient is in a target activity state, e.g., an activity state in which lead impedance testing will be unobtrusive, such as when a patient is asleep, or capture information of particular interest, such as when the patient is active, in a particular posture, or changing postures. The implantable medical device performs the lead functionality test based on this determination. Additionally, in some embodiments, the implantable medical device may group a plurality of measurements for a single lead functionality test into a plurality of sessions, and perform the measurement sessions interleaved with delivery of therapeutic stimulation.
