Abstract
An implantable medical system that includes a cardiac therapy module and a neurostimulation therapy module may identify when neurostimulation electrodes have migrated toward a patient's heart. In some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on a physiological response to an electrical signal delivered to the patient via the neurostimulation electrodes. In addition, in some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on an electrical cardiac signal sensed via the neurostimulation electrodes.
Claims37
A method comprising:
- delivering cardiac rhythm therapy to a heart of a patient via a first set of electrodes of a first lead electrically connected to a cardiac therapy module;
- delivering an electrical stimulation signal to a tissue site within a patient via a second set of electrodes of a second lead electrically connected to a neurostimulation therapy module;
- sensing an electrical cardiac signal with the second set of electrodes of the second lead, wherein the electrical cardiac signal is generated by the heart of the patient;
- determining whether the electrical cardiac signal indicates the second set of electrodes of the second lead is at least a predetermined distance away from the heart of the patient;
- and
- controlling the neurostimulation therapy module to deliver neurostimulation therapy to the patient in response to determining the electrical cardiac signal indicates the second set of electrodes of the second lead is at least the predetermined distance away from the heart.
