Methods and systems for lowering blood pressure through reduction of ventricle filling
First Claim
1. A system for reducing blood pressure in a patient having a pretreatment blood pressure, comprising:
- at least one stimulation electrode for stimulating at least one chamber of a heart of the patient; and
at least one controller configured to execute a stimulation pattern comprising multiple stimulation pulses,wherein at least one stimulation pulse of the multiple stimulation pulses has a first stimulation setting configured to reduce atrial kick in at least one ventricle of the heart, andwherein at least one stimulation pulse of the multiple stimulation pulses has a second stimulation setting configured to reduce a baroreflex response to a reduction in blood pressure resulting from the reduction in atrial kick.

Abstract
Methods and devices for reducing ventricle filling volume are disclosed. In some embodiments, an electrical stimulator may be used to stimulate a patient'"'"'s heart to reduce ventricle filling volume or even blood pressure. When the heart is stimulated in a consistent way to reduce blood pressure, the cardiovascular system may over time adapt to the stimulation and revert back to the higher blood pressure. In some embodiments, the stimulation pattern may be configured to be inconsistent such that the adaptation response of the heart is reduced or even prevented. In some embodiments, an electrical stimulator may be used to stimulate a patient'"'"'s heart to cause at least a portion of an atrial contraction to occur while the atrioventricular valve is closed. Such an atrial contraction may deposit less blood into the corresponding ventricle than when the atrioventricular valve is opened throughout an atrial contraction.
