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 with a stimulation pattern comprising at least one stimulation pulse; and
at least one controller configured to;
receive input relating to the patient'"'"'s blood pressure; and
adjust the stimulation pattern based on the blood pressure.

Abstract
Systems and methods for reducing ventricle filling volume are disclosed. In some embodiments, a stimulation circuit may be used to stimulate a patient'"'"'s heart to reduce ventricle filling volume or even blood pressure. When the heart is stimulated at a consistent rate 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, a stimulation circuit 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.

23. A system for reducing blood pressure comprising:
-
at least one stimulation electrode for stimulating at least one chamber of a heart of a patient with a stimulation pulse; and a controller configured to; provide a first stimulation pattern comprising at least one stimulation setting configured to reduce or prevent atrial kick in at least one ventricle for a first time interval and to receive a first input data set relating to a patient'"'"'s blood pressure during said first time interval; calculate at least one blood pressure variation parameter relating to the first input data set; adjust at least one parameter of a second stimulation pattern comprising a second stimulation setting configured to reduce or prevent atrial kick in at least one ventricle, the second stimulation setting being based upon the at least one blood pressure variation parameter; and provide the second stimulation pattern for a second time interval.
