Abstract

The method calls for the periodic electrical stimulation of the heart muscle to alter the ejection profile of the heart thus reducing the observed blood pressure of the patient. The therapy may be invoked by an implantable blood pressure sensor associated with a pacemaker like device.

Claims

1. A method, carried out with an implanted heart muscle stimulator, for treating blood pressure disorders in a patient comprising the steps of:

measuring the patient'"'"'s pre treatment blood pressure (BP), with an external or implanted sensor, corresponding to both a pretreatment cardiac ejection profile and a pretreatment cardiac contractility profile;

comparing the measured pre treatment blood pressure with a treatment threshold;

stimulating the patient'"'"'s heart with an electrical stimulus at one or more times and/or locations to alter the cardiac ejection profile thereby reducing the measured blood pressure from the pretreatment blood pressure value.

2. The method of claim 1 wherein the stimulating step comprises:

placing a lead in the RV right ventricle of the heart and coupling the lead to said muscle stimulator.

3. The method of claim 1 wherein the stimulating step comprises:

placing a lead in the LV left ventricle of the heart and coupling the lead to said muscle stimulator.

4. The method of claim 1 wherein the stimulating step comprises:

placing a lead in the LV left ventricle of the heart and placing a lead in the RV right ventricle and coupling each of said leads to said muscle stimulator.

5. The method of claim 1 wherein the stimulating step comprises:

placing a first lead at a first location in the RV right ventricle of the heart and placing a second lead at a second location different from said first location in the RV right ventricle and coupling each of said leads to said muscle stimulator.

6. The method of claim 1 wherein the stimulating step comprises:

placing a first lead at a first location in the LV left ventricle of the heart and placing a second lead at a second location different from said first location in the LV left ventricle and coupling each of said leads to said muscle stimulator.

7. The method of claim 1 wherein the stimulating step comprises:

placing a first lead at a first location in the RA right atrium of the heart and placing a second lead at a second location in the LV left ventricle and coupling each of said leads to said muscle stimulator.

8. The method of claim 1 wherein the stimulating step comprises:

placing a first lead at a first location in the RA right atrium of the heart and placing a second lead at a second location in the RV right ventricle and coupling each of said leads to said muscle stimulator.
