Abstract

A programmer including a user interface, and techniques for programming a rate responsive implantable medical device using such a programmer and user interface are presented. The programmer may retrieve currently programmed rate response parameters and optimization target values of an implantable medical device. The programmer may display the currently programmed rate response parameters and optimization target values via a user interface. The programmer may also generate a current rate response curve and a current target rate histogram, and display the current rate response curve and current target rate histogram via the user interface. The programmer may receive changes to the displayed currently programmed rate response parameters and/or target values made by a user via the user interface, generate a pending rate response curve and/or a pending target rate histogram based on these changes, and display the pending rate response curve and/or pending target rate histogram via the user interface.
