Abstract

A monitoring device is provided to monitor a patient. The monitoring device includes at least one lead having an electrode. The lead is positioned proximate a location within the patient'"'"'s body, and the lead is adapted to sense cardiac electrical activity. The monitoring device also includes a control system coupled to the at least one lead to receive a signal representative of the cardiac electrical activity.

Claims

1. A monitoring device that monitors a patient, comprising:

at least one lead having an electrode, positioned proximate a location within a body of the patient and adapted to sense cardiac electrical activity; and

a control system coupled to the at least one lead to receive a signal representative of the cardiac electrical activity.

2. The monitoring device of claim 1, wherein the at least one lead is positioned proximate a location selected from one of a carotid artery and a carotid sinus.

3. The monitoring device of claim 1, wherein the control system is adapted to generate an electrocardiogram based on the cardiac electrical activity sensed by the at least one lead.

4. The monitoring device of claim 3, wherein the control system is further adapted to store the electrocardiogram.

5. A baroreflex activation system, comprising:

at least one lead having an electrode at a distal end, positioned proximate a location within the body of a patient and adapted to sense cardiac electrical activity;

a control system coupled to the at least one lead and to receive a signal representative of the cardiac electrical activity, and to deliver a baroreflex therapy through the at least one lead.

6. The baroreflex activation system of claim 5, wherein the baroreflex therapy is delivered in response to the cardiac electrical activity sensed by the at least one lead.

7. The baroreflex activation system of claim 5, wherein the at least one lead is positioned proximate a baroreflex site selected from one of a carotid artery and a carotid sinus.

8. The baroreflex activation system of claim 5, wherein the control system is adapted to generate an electrocardiogram based on the sensed cardiac electrical activity.

9. A method of monitoring cardiac activity and applying a baroreflex therapy for a patient, comprising:

implanting a baroreflex activation system within a body of the patient, the baroreflex activation device including a control system and at least one electrode, the at least one electrode adapted to deliver a signal and to sense cardiac electrical activity;

positioning the at least one electrode at a location within the body of a patient;

causing the baroreflex activation system to sense cardiac electrical activity via the at least one electrode; and

causing the baroreflex activation system to deliver a baroreflex therapy.

10. The method of claim 9, wherein the baroreflex therapy delivered by the baroreflex activation system is modulated in response to the sensed cardiac electrical activity.

11. The method of claim 10, wherein the control system generates an electrocardiogram based on the sensed electrical cardiac activity by the at least one electrode.

12. The method of claim 11, wherein the at least one electrode is positioned proximate a baroreflex site selected from one of a carotid artery and a carotid sinus.

13. A method of monitoring cardiac activity for a patient, comprising:

providing at least one lead having an electrode adapted to sense a cardiac parameter;

providing a control system adapted to be coupled to the at least one lead to receive signals from the at least one lead representative of the cardiac parameter; and

providing instructions to position the at least one lead proximate a first location within a body of the patient.

14. The method of claim 13, wherein the control system is adapted to generate an electrocardiogram based on the sensed cardiac electrical activity.

15. The method of claim 14, wherein providing instructions to position the at least one lead comprises providing instructions to position the at least one lead proximate a baroreflex site selected from one of a carotid artery and a carotid sinus.
