Cardiac stimulation device and method for automatic lower pacing rate optimization
First Claim
1. A method for controlling delivery of a therapy in an implantable medical device, comprising:
- delivering a therapy at a first rate during a first time period;
monitoring a parameter in response to the therapy delivered at the first rate to generate first parameter data;
determining whether the therapy was delivered for a predetermined portion of the first time period;
delivering the therapy at a next rate during a next time period;
monitoring the parameter in response to the therapy delivered at the next rate to generate next parameter data;
determining whether the therapy was delivered for a predetermined portion of the next time period;
determining a metric corresponding to the first parameter data to generate a first parameter metric, and to the next parameter data to generate a next parameter metric; and
determining one of the first rate and the next rate as an optimal therapy delivery rate in response to the first parameter metric and the next parameter metric.

Abstract
A method and device for determining an optimal lower rate and adjusting the programmed lower pacing rate to the optimal rate that includes monitoring a parameter in response to therapy delivered at a first rate during a first time period to generate first parameter data, and determining whether the therapy was delivered for a predetermined portion of the first time period. The parameter is monitored in response to the therapy delivered at a next rate during a next time period to generate next parameter data, and a determination is made as to whether the therapy was delivered for a predetermined portion of the next time period. A metric corresponding to the first parameter data is determined to generate a first parameter metric, and corresponding to the next parameter data to generate a next parameter metric used for determining an optimal therapy delivery rate.
