VDD lead-lead interaction and atrial oversensing: an acute animal study.
Limited data exist on the utilization of a transvenous A-sense; V-pace/sense (VDD)pacing system with a chronically retained nonfunctioning endocardial V-sense/pace (VVI)pacing lead. In an acute canine model, no atrial oversensing was observed with lead-lead interaction between the VDD lead and the pseudo-retained VVI lead. Undersensing occurred <10% of all beats observed.
