Abstract

The invention presents techniques for processing an atrial electrogram. An atrial electrogram senses atrial events, but may also sense a ventricular event, causing a far field R-wave to be present in the atrial electrogram signal. A far field R-wave is an undesired artifact. The invention provides techniques for estimating the far field R-wave and subtracting the far field R-wave from the atrial electrogram signal.
