摘要
A pace responsive cardiac pacemaker for providing an optimized pacing rate of stimulation pulses as a function of at least one selected rate control parameter. Each rate control parameter has a value which varies as a function of changes in a patient's physiologic demand and includes a sensor system for sensing the rate control parameter value and for providing a sensor output representative thereof. The cardiac pacemaker also includes a rate response defining means for deriving desired pacing rates as a function of the sensor output, an achievement monitoring means that has a predetermined achievement criterion (primary criterion), for monitoring the relationship between the derived pacing rates and the achievement criterion over an optimization period.
