Hi Angie,
So we have a robust and yet simple protocol for our LBBaP patients. I feel that without an EKG, it's not a true conduction system interrogation for the initial post implant check (post op and at first in office follow-up). The TLDR version is - post implant we do EKG with whatever outputs set (bipolar) by the implanter. we document LBBaP paced morphology and measure Stim-Peak (LV activation/RWave Peak time) in V5 or V6 and document it. At their 1 month check, we repeat the EKG after chronic outputs are set (bipolar) and if no significant change in morphology or Stim-peak that's it. Early on I treated these patients similar to HIS bundle patients and had their follow-ups set to have 12 lead rhythm strips in unipolar and bipolar configuration documenting threshold and changes with decrementing outputs (at 1, 3, 6, and 12monts), but found that it didn't change any thing long term and only led to unnecessarily long follow-up visits. If there is ever an issue at the 1 month check, they come back at 3-6 months and I'll do the full gambit, but in the last 18 months I've only had to do this maybe three times.
When correctly placed, the LBBaP leads are very stable in my experience and don't require a lot of robust follow-up. After their first in office visit, we see them generally once a year for an annual check and otherwise remotely monitor unless they need to come sooner.
Hopefully this helps!
