Cardiac Stimulation Apparatus And Method For The Control Of Hypertension
First Claim
1. A method, carried out with an implanted heart muscle stimulator associated with a heart of a patient, for treating a blood pressure disorder in the patient, the patient having a pretreatment blood pressure corresponding to a pretreatment cardiac ejection profile, the method comprising:
- stimulating the patient'"'"'s heart with an electrical stimulus timed relative to the patient'"'"'s cardiac ejection cycle to cause dyssynchrony between at least two cardiac chambers and alter the patient'"'"'s cardiac ejection profile from the pretreatment cardiac ejection profile, thereby reducing the patient'"'"'s blood pressure from the pretreatment blood pressure.

Abstract
A method that electrically stimulates a heart muscle to alter the ejection profile of the heart, to control the mechanical function of the heart and reduce the observed blood pressure of the patient. The therapy may be invoked by an implantable blood pressure sensor associated with a pacemaker like device. In some cases, where a measured pretreatment blood pressure exceeds a treatment threshold, a patient'"'"'s heart may be stimulated with an electrical stimulus timed relative to the patient'"'"'s cardiac ejection cycle. This is done to cause dyssynchrony between at least two cardiac chambers or within a cardiac chamber, which alters the patient'"'"'s cardiac ejection profile from a pretreatment cardiac ejection profile. This has the effect of reducing the patient'"'"'s blood pressure from the measured pretreatment blood pressure.
