Methods and systems for controlling blood pressure by controlling atrial pressure
First Claim
1. A system for reducing blood pressure in a patient, the system comprising:
- a stimulation circuit configured to deliver a stimulation pulse to at least one cardiac chamber of a heart of the patient; and
at least one controller configured to execute delivery of one or more stimulation patterns of stimulation pulses to the at least one cardiac chamber,wherein at least one of the stimulation pulses stimulates the heart to cause increased atrial stretch of a wall of an atrium as a result of timing of atrial contraction and ventricular contraction, andwherein the increased atrial stretch is higher than an atrial stretch would be without the stimulation, such that the blood pressure of the patient is reduced.

Abstract
Systems and methods for controlling blood pressure by controlling atrial pressure and atrial stretch are disclosed. In some embodiments, a stimulation circuit may be configured to deliver a stimulation pulse to at least one cardiac chamber of a heart of a patient, and at least one controller may be configured to execute delivery of one or more stimulation patterns of stimulation pulses to the at least one cardiac chamber, wherein at least one of the stimulation pulses stimulates the heart such that an atrial pressure resulting from atrial contraction of an atrium overlaps in time a passive pressure build-up of the atrium, such that an atrial pressure of the atrium resulting from the stimulation is a combination of the atrial pressure resulting from atrial contraction and the passive pressure build-up and is higher than an atrial pressure of the atrium would be without the stimulation, and such that the blood pressure of the patient is reduced.

19. A method, carried out with an implanted heart muscle stimulator associated with a heart of a patient, for reducing blood pressure of the patient, the method comprising:
-
delivering one or more stimulation patterns of stimulation pulses to at least one cardiac chamber of the heart of the patient; and stimulating the heart with at least one of the stimulation pulses to cause increased atrial stretch of a wall of an atrium as a result of timing of atrial contraction and ventricular contraction, wherein the increased atrial stretch is higher than an atrial stretch would be without the stimulation, such that the blood pressure of the patient is reduced. - View Dependent Claims (20)
