The third method is the iterative method where the operator starts with an AV delay
programming that causes ventricular pre-excitation.
The optimal AV delay
was determined to be between 5 and 20 ms (18).
Other competitive features include SMART Success IEGM storage, Mode Conversion with programmable ventricular rate support, Dynamic AV Delay
to mimic normal physiologic shortening with exercise, Real-time IEGMs to facilitate troubleshooting and programming, along with a sophisticated EP Test Mode to evaluate defibrillation therapy thresholds and the efficacy of anti-arrhythmic drug therapy.

and V-V interval are dynamically changed through an automated closed-loop optimization process, using the neural network processor input of the individual patterns, to constantly optimize patient's cardiac output and quality of life.
In addition to the SMART Detection(TM) Algorithm, the PHYLAX AV provides dual-chamber pacing with Dynamic Hysteresis and Dynamic AV Delay
to optimize hemodynamics.
DOD pacing with short AV delay
may result in hemodynamic and symptomatic improvement (16-19).
The BEST LIVING system can monitor and optimize therapy effectiveness and has the unique ability to determine the best stimulation configuration as well as AV Delay
and VV interval.
