US 11,141,594 B2 · Pacing-based hypertension therapy pacing rate adjustment

Abstract

This document discusses, among other things, systems and methods to generate a first pacing waveform during a first pacing period and a second pacing waveform during a second pacing period, to alternate first and second pacing periods to provide pacing-based hypertension therapy to a heart of a patient to reduce patient blood pressure, and to determine an increased pacing rate for the first pacing waveform during the first pacing period using the first AV delay, wherein the first pacing waveform has a first atrioventricular (AV) delay and the second pacing waveform has a second AV delay longer than the first AV delay.

Claims20

Dependent claims

A system comprising:

a stimulation circuit configured to generate first and second pacing waveforms;
an assessment circuit configured to control generation of the first and second pacing waveforms, including to control generation of the first pacing waveform having a first atrioventricular (AV) delay during a first pacing period and the second pacing waveform having a second AV delay, longer than the first AV delay, during a second pacing period, and to alternate the first and second pacing periods to provide pacing-based hypertension therapy to a heart of a patient to reduce patient blood pressure,
wherein the assessment circuit is configured to determine an increased pacing rate for the first pacing waveform using the first AV delay, the increased pacing rate in contrast to a pacing rate of the second pacing waveform.

At least one non-transitory machine-readable medium including instructions that, when performed by a medical device, cause the medical device to:

generate a first pacing waveform during a first pacing period and a second pacing waveform during a second pacing period, and alternate the first and second pacing periods to provide pacing-based hypertension therapy to a heart of a patient to reduce patient blood pressure, wherein the first pacing waveform has a first atrioventricular (AV) delay and the second pacing waveform has a second AV delay longer than the first AV delay;
and
determine an increased pacing rate for the first pacing waveform during the first pacing period using the first AV delay, the increased pacing rate in contrast to a pacing rate of the second pacing waveform.
