■
Sensed AV Interval (SAV). SAV follows an atrial sensed event in atrial
synchronous pacing modes (DDDR, DDD, and VDD). The SAV
interval duration may differ from the programmed value due to:
- Rate Adaptive AV operation or
- Wenckebach operation, where the SAV is extended to avoid
violation of the Upper Tracking Rate or the total atrial refractory
period while tracking a fast intrinsic atrial rate (refer to “High Rate
Atrial Tracking” later in this chapter).
