TPM... AAI vs VVI c tx of bradycardia

[RN12345656]

I work on a cardiac surgery step-down floor. The other day I had an orientee and I was trying to explain to her modes AAI and VVI on temporary pacemakers. I explained to her that if she had a patient with bradycardia it is best to pace VVI or DDD. I also explained she would see atrial pacing on pts who underline NSR and the benefits of that atrial kick. >>>>>My question is this: My orientee asked, "Why can't you pace a pt with bradycardia in AAI mode". Well I guess you can, but why is it better to pace VVI vs AAI? Can someone explain in depth for me? Thanks! :)

This is so far out of my practice, but I am waiting with baited breath....love the debate.

Dinith,

This is an exercise in futility that I will now bow out of as you cannot think outside of your box to understand the concept, an impulse such as the shock delivered by a TPM will cause some contraction, it may be a small contraction, however, it will be a more efficient/productive contraction than that of a fibrillating atria, that is why this works. You've already shown you don't fully understand how a pace maker is triggered, thinking that rate is the only trigger, and I'd be willing to guess that you really don't do much with the pacemakers as much as play go-fer for the doc's you work with so I will let this one go, I AM FINISHED!!! I know you will reply with some tort, but I am done. is over.

This must become an agree to disagree as when one argues with an idiot, it is difficult to tell who the idiot is, therefore I will remove myself from the argument to make it more clear.

Dinith, it is difficult to tell who the idiot is, therefore I will remove myself from the argument to make it more clear.
