1. A dual chamber pacemaker system, having atrial sense means for sensing signals from a patient'"'"'s atrium, ventricular sense means for sensing ventricular signals from a patient, ventricular pace means for generating and delivering ventricular pacing pulses to said patient'"'"'s right ventricle, AVesc means for setting and timing an AV escape interval from the occurrence of a sensed atrial signal, sync control means for controlling delivery of ventricular pacing pulses at the time out of said AV escape interval in the absence of a sensed ventricular signal, and FFRS means for detecting FFRSs following delivered ventricular pacing pulses, further comprising FFRS analyzing means for analyzing said detected FFRSs and determining therefrom an indication for adjustment of said AV escape interval, said AVesc means having adjusting means for adjusting said AV escape interval in accordance with said indication.
