May favor proximal ventricular electrodes for far-field P-wave detection; leaves open single-lead atrioventricular synchronous pacing.
Does intraventricular electrogram morphology analysis from a proximal electrode improve far-field P wave detection accuracy compared to a distal electrode in patients with ventricular leads?
Far-field detection of atrial activation is more accurate at the proximal ventricular electrode, suggesting feasibility for P wave synchronous pacing from a single standard ventricular lead.
Greenhut et al. (1993) studied this question.
