Abstract

During auto-threshold, autocapture, or other evoked response sensing, post-pace artifact is reduced by using a smaller coupling capacitor value than what is used when not in such an evoked response sensing configuration. This can be accomplished by borrowing another capacitor for use as the coupling capacitor. The borrowed capacitor can be a backup pacing capacitor from the same or a different pacing channel. The borrowed capacitor can also be a coupling capacitor from a different pacing channel.

First claim

What is claimed is:

1. A method comprising:
providing an implantable medical device including:
a first electrostimulation voltage generator;
a first capacitor having a first capacitance value, coupled to the electrostimulation voltage generator, wherein the first capacitor and the electrostimulation generator are arranged in a first pacing channel;
a second capacitor having a second capacitance value; and
a third capacitor having a third capacitance value, wherein the third…
