Feasibility of far-field ventricular sensing from atrial leads may aid DDD(R) algorithms; leaves open prospective validation before practice change.
Observational (n=200)
Accurate sensing of far-field ventricular signals from an atrial pacing lead is feasible in most patients, which may help improve physiological atrial rate responsive and DDD(R) pacing algorithms.
Brouwer et al. (1997) conducted an observational in Pacemaker implantation (n=200). Atrial sensed far-field ventricular signal vs. Atrial deflection was evaluated on Amplitude and slew rate of the far-field ventricular signal. The amplitude and slew rate of the far-field ventricular signal were significantly smaller than those of the atrial deflection in patients undergoing pacemaker implantation.
