Abstract

An exemplary includes acquiring an electroneurogram of the right carotid sinus nerve or the left carotid sinus nerve, analyzing the electroneurogram for at least one of chemosensory information and barosensory information and calling for one or more therapeutic actions based at least in part on the analyzing. Therapeutic actions may aim to treat conditions such as sleep apnea, an increase in metabolic demand, hypoglycemia, hypertension, renal failure, and congestive heart failure. Other exemplary methods, devices, systems, etc., are also disclosed.

Claims

1. A method comprising:

acquiring an electroneurogram of the right carotid sinus nerve or the left carotid sinus nerve;

storing the electroneurogram in memory of an implantable device;

communicating the stored electroneurogram to another device; and

analyzing the electroneurogram for at least one of chemosensory information and barosensory information.

2. The method of claim 1 further comprising calling for one or more therapeutic actions based at least in part on the analyzing.

3. The method of claim 1 further comprising instructing the implantable device to call for one or more therapeutic actions based at least in part on the analyzing.

4. The method of claim 1 wherein the analyzing comprises comparing at least one of the chemosensory information and the barosenory information to historic information.

5. The method of claim 1 wherein the analyzing comprises use of at least one established relationship between carotid sinus nerve activity and blood pressure.

6. The method of claim 1 wherein the analyzing comprises use of at least one established relationship between carotid sinus nerve activity and blood chemistry.

7. The method of claim 1 further comprising making a diagnosis based at least in part on the analyzing.

8. The method of claim 7 wherein the diagnosis comprises a member selected from a group consisting of sleep apnea, an increase in metabolic demand, hypoglycemia and hypertension.
