I'm just curious.
Currently I have a CHB without a PM.
Without a PM, the AV node is pacing itself at a lower rate, hence the 30-40bpm bradycardia commonly found in CHB people.
My understanding is that a pacer will "follow" the SA node to trigger the AV node, with an appropriate delay .
So when a PM, would the AV node continue its original independent pacing in addition to the one induced by the PM? Does the PM wait for the AV self-pulse to occur and only trigger it when it doesn't?
