WebThe consequence of FFRW oversensing are (1) inappropriate mode switching in a dual-chamber system and (2) pacing below the programmed rate in an AAI (R) pacemaker. A number of different factors may favor FFRW oversensing ( Box 37-7 ): • Short PVAB. The prerequisite for FFRW oversensing is that the FFRW falls outside of the PVAB. • WebMar 11, 1999 · Mode-switch algorithm of the Chorum pacemaker. For explanation see text.
