AV Intervals
Overview
In dual chamber modes, the AV intervals determine the time between the
occurrence of an atrial event and the scheduled delivery of a ventricular
stimulus. Separate AV intervals for paced and sensed atrial events are
available. The lengths of these intervals may be programmed to fixed
values or (optionally) rate adaptive.
■
Paced AV Interval (PAV). PAV follows an atrial pace in the DDDR,
DDD, DDIR, DDI, DVIR, DVI, DOOR, and DOO modes. The PAV
interval duration may differ from the programmed value due to:
- Rate Adaptive AV operation,
- Ventricular Safety Pacing, or
- Non-Competitive Atrial Pacing operation.
