Streamlined Follow-ups
Faster access to key diagnostic data.
- Daily automatic measurements may eliminate the need for in-clinic testing
- RF and 64K telemetry means interrogations are up to three times faster to help reduce follow-up times1
- Remote follow-up can be scheduled to take place automatically, with no patient interaction required (RF model only)

Intelligent Optimization
Simple solutions deliver optimal therapy based on patient needs.
- Comprehensive atrial arrhythmia management tools help ensure consistent therapy delivery
- AT/AF alerts can be set to notify patients and their clinics when a programmed threshold has been exceeded
-
AF Suppression™ algorithm is clinically proven to suppress episodes of paroxysmal and persistent AF1
- Triggered Pacing with BiV Trigger Mode promotes continuous BiV pacing, especially during AF, by triggering pacing in both ventricles in response to a sensed ventricular event
- VectSelect™ programmable LV pulse configuration has four LV pacing vectors and allows lead adjustment to take place non-invasively using the programmer, saving time at implant and reducing the need for reoperation
- Negative AV Hysteresis with search helps minimize the risk of losing BiV pacing by automatically reducing AV delay when intrinsic activity is present
-
QuickOpt™ Timing Cycle Optimization provides quick and effective AV and V-to-V optimization at the touch of a button to help improve patient outcomes
Enhanced Safety and Reliability
Design provides earlier detection of some clinical events.
- Programmable audible alerts can notify patients to changes in device performance
- Industry-leading longevity of 7.8 years2 – with stored electrograms turned on – is backed by a five-year warranty
- Multiple hardware and software system safeguards ensure therapy delivery, even in the unlikely event of individual component failures
