Cardiac rhythm management system with user interface for threshold test
First Claim
1. A cardiac rhythm management system including:
- an external user interface, the user interface including a communication module, adapted for remote communicative coupling to an implantable device;
a threshold testing module, adapted for initiating therapy delivery by the implantable device at energies that vary between one or more instances of therapy delivery by the implantable device; and
a recorded output indicator of energy associated with an instance of therapy delivery by the implantable device.

Abstract
An implantable cardiac rhythm management system includes a user interface, such as an external programmer, for performing therapy energy threshold tests. The threshold tests allow the caregiver to determine the threshold energy at which paces capture the heart, i.e., cause a resulting contraction of the heart chamber to which the paces are delivered. The programmer provides recorded indications of the energy corresponding to each paced event, so that the caregiver can easily determine the point at which capture was lost. This recorded representation of pacing energy makes it easy for the caregiver to determine proper pacing thresholds to be used to ensure adequate pacing, while minimizing energy drain to prolong the useful life of the implanted device.
