Abstract
An implantable cardiac rhythm management device is configured to remove pacing artifacts from recorded electrograms by a subtraction method. A template waveform representing a recorded pace without accompanying cardiac electrical activity is generated. Such a pacing pulse template is then aligned with the instant at which a pace is delivered and subtracted from the recorded electrogram in order to remove the pacing artifact.
