Methods and Systems for Lowering Blood Pressure Through Reduction of Ventricle Filling
First Claim
1. A system for reducing blood pressure comprising:
- at least one stimulation electrode for stimulating at least one chamber of a heart of a patient; and
at least one controller that executes a stimulation pattern comprising at least one stimulation pulse having at least one stimulation setting that reduces or prevents atrial kick in at least one ventricle of the heart,wherein the at least one stimulation setting causes an atrium of the heart to be at maximum contraction when an atrioventricular valve of the heart is open.

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.
