Methods and systems for automatically switching electrode configurations
First Claim
1. A method for measuring an evoked response signal to allow automatic capture detection to automatically continue functioning upon an automatic change of a sensing electrode configuration of an implantable stimulation device, the method comprising:
- automatically determining whether a current sensing electrode configuration that is being used to measure an evoked response signal to ascertain whether capture has occurred is unable to be used for that purpose;
automatically switching to at least one other different sensing electrode configuration to measure the evoked response signal to ascertain whether capture has occurred;
performing an automatic recalibration procedure with the different sensing electrode configuration; and
automatically using the different sensing electrode configuration to measure evoked response signals to allow the automatic capture detection to continue functioning upon the automatic change of a sensing electrode configuration.

Abstract
Various embodiments can permit electrode configurations that are used in implantable devices to be automatically changed. In some embodiments, configurations that are used to ascertain capture (ventricular and/or atrial) can be automatically changed by a stimulation device and then automatically configured for use. Various parameters associated with the electrical configurations can be automatically calibrated so that a stimulation device'"'"'s automatic capture feature can continue to function notwithstanding the fact that an electrode configuration change has taken place.
