Abstract
Various system embodiments comprise a stimulator adapted to deliver a stimulation signal for a heart failure therapy, a number of sensors adapted to provide at least a first measurement of a heart failure status and a second measurement of the heart failure status, and a controller. The controller is connected to the stimulator and to the number of sensors. The controller is adapted to use the first and second measurements to create a heart failure status index, and control the stimulator to modulate the signal using the index. Other aspects and embodiments are provided herein.
Claims20
A method, comprising:
- delivering a therapy using an implantable device to electrically stimulate a heart muscle or an autonomic neural target using stimulation parameters;
- receiving parameter values, wherein the received parameter values include parameter values for at least a respiration parameter and a heart sound parameter;
- using an algorithm to process the received parameter values;
- and
- changing the stimulation parameters based on the processed received parameter values.
A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to:
- deliver a therapy using an implantable device to electrically stimulate a heart muscle or an autonomic neural target using stimulation parameters;
- receive parameter values, wherein the received parameter values include parameter values for at least a respiration parameter and a heart sound parameter;
- use an algorithm to process the received parameter values;
- and
- change the stimulation parameters based on the processed received parameter values.
A system, comprising:
- an implantable heart failure therapy delivery system configured to deliver a heart failure (HF) therapy to electrically stimulate a heart muscle or an autonomic neural target;
- and
- control circuitry operably connected to the therapy delivery system and configured to:
- receive parameter values, wherein the received parameter values include parameter values for at least a respiration parameter and a heart sound parameter;
- generate at least a first HF status index and a second HF status index from the received parameter values;
- and
- change the electrical stimulation based on the received parameter values.
