Abstract
Far field reduction is carried out in a cardiac electrogram by extracting unipolar beats of an intracardiac electrogram that occur within a predetermined time interval that includes QRS peaks, constructing a first mean unipolar beat by averaging the extracted unipolar beats, and accepting unipolar beats that cross-correlate with the first mean unipolar beat. A second mean unipolar beat is constructed from the accepted unipolar beats. A ventricular far field component is determined from the extracted unipolar beats and subtracted from the intracardiac electrogram to distinguish a local component of the intracardiac electrogram.
