WARAD vs. PVARP

EP here. I would like to hear your thoughts on the differences pros/cons on your WARAD algorithm and how it compares to the standard PVARP timing cycle.

What a way to step up and sell your product Sorin, this is exactly why you guys are a joke and I turned you down when you approached me! 178 views and nobody answered the guys question~ hahahhaha

Then why don't you Google it Mr. 'EP' ? Good Lord, can't you do anything for yourselves? Sorry, Dr. 'EP', though I doubt you really are. MORE THAN LIKELY JUST ANOTHER BUTTON PUSHING BIG BLUE EX-PHARMA MONKEY.

Failure to reports deaths and injuries due to lead malfunctions to the FDA. Who's mistaken?

Check....and......mate.
I don't work for Sorin but ot the poster above talking trash to the EP. Even if you don't suspect he is an EP there is no way to prove it, your really just showing what an asshole you are. Even if there is a 1% chance he is an EP you can't afford to make enemy's. clearly you are not a salesman. Even if it is just a "button pushing pharma" or whatever, the person is interested in your technology, so use it as an opportunity to sell. Your professionalism is unbelievable.
 






SIGH.....It works like this, my little troll, ....no self respecting EP has ever even looked at this POS site. Ever, nada, done, never. Thus the previous post. Can you make 7 figures in CRM? I think we know the answer to be no. I can and do. Any EP with the Warad question will ask another EP buddy of theirs to avoid corporate BS. You've never sold anything in your life and it shows. Now please shut up and sit down.
 






"People mock that which they not understand."

WARAD (Window of Atrial Rate Acceleration Detection) is a purely atrial based adapative TARP algorithm based on calculation of TARP from a percentage of the previous normal A-A interval(s). Except for post-PVC function, there is no PVARP in Sorin devices. PVARP is non-physiologic; there is no natural refractory period in the heart that corresponds to it; it is the reason why there are many programming limitations in devices that depend on it. With WARAD, the TARP is determined by the patients own natural changes in rate; not arbitrary programmed values. It distinguishes "normal" events from "pathological" events.

FMS (Fallback Mode Switching) algorithm is closely tied to it. The mode switching algorithm is based on statistical analysis. First, PAC sensed in WARAD puts FMS into suspicion phase. During suspicion phase, ventricle cannot track faster than 120 bpm. FMS looks for a "strong" or "weak" criterion based on number of V cycles with A events falling into WARAD. If criterion is met, then mode switch to DDI occurs. This analysis allows for atrial undersensing to occur during mode switch. Traditional "rate vs run" algorithms can result in V tracking to the max rate and are dependant on 100% atrial sensing.
