Abstract
Techniques for determining whether a lead related condition exists based on a correlation between a parameter indicative of impedance of a lead and a parameter indicative of motion of the lead. In some examples, the techniques include generating an electrical signal that is indicative of impedance of the lead, generating an electrical signal that is indicative of motion of the lead, and monitoring the frequency, amplitude, and phase of the electrical signals in order to identify a correlation. In some examples, if a lead related condition is identified, an alert is provided or a sensing or therapy modification is suggested.
