Abstract
A lower pacing rate limit is utilized by pacing devices to initiate pacing in response to a patient's intrinsic rate being less than the lower pacing rate limit. Illustrative systems, devices, and methods may obtain rate modification information related to a patient such as physical characteristics, diagnostic parameters, pathologies, device characteristics of a pacing device implanted in the patient, and patient-reported information. The rate modification information may be used to determine lower pacing rate limit based thereon.
Claims33
A method comprising:
- obtaining rate modification information comprising at least one physical characteristic of a patient utilizing a pacing device and at least one diagnostic parameter, the at least one diagnostic parameter comprising a nighttime heart rate;
- receiving an upper bound, a lower bound, and a percentage of pacing threshold;
- and
- determining a lower pacing rate limit for the pacing device based on the obtained rate modification information, the upper bound, the lower bound, and the percentage of pacing threshold, wherein the lower pacing rate limit is increased when a percentage of paced beats exceeds the percentage of pacing threshold and wherein the lower pacing rate limit is utilized by the pacing device to initiate pacing in response to the patient's intrinsic rate being less than the lower pacing rate limit.
A system comprising:
- a computing apparatus comprising one or more processors and configured to:
- obtain rate modification information comprising at least one physical characteristic of a patient utilizing a pacing device and at least one diagnostic parameter, the at least one diagnostic parameter comprising a nighttime heart rate;
- receive an upper bound, a lower bound, and a percentage of pacing threshold;
- and
- determine a lower pacing rate limit for the pacing device based on the obtained rate modification information, the upper bound, the lower bound, and the percentage of pacing threshold, wherein the lower pacing rate limit is increased when a percentage of paced beats exceeds the percentage of pacing threshold and wherein the lower pacing rate limit is utilized by the pacing device to initiate pacing in response to the patient's intrinsic rate being less than the lower pacing rate limit.
An implantable medical device comprising:
- one or more electrodes to deliver cardiac pacing therapy to and sense electrical activity from a patient's heart;
- and
- a computing apparatus operably coupled the one or more electrodes and comprising one or more processors, the computing apparatus configured to:
- monitor the patient's intrinsic heart rate using the one or more electrodes;
- deliver pacing therapy to the patient's heart in response to the patient's intrinsic rate being less than a lower pacing rate limit;
- obtain rate modification information comprising at least one physical characteristic of a patient utilizing a pacing device and at least one diagnostic parameter, the at least one diagnostic parameter comprising a nighttime heart rate;
- receive an upper bound, a lower bound, and a percentage of pacing threshold;
- and
- determine a lower pacing rate limit for the pacing device based on the obtained rate modification information, the upper bound, the lower bound, and the percentage of pacing threshold, wherein the lower pacing rate limit is increased when a percentage of paced beats exceeds the percentage of pacing threshold.
