What is the right approach in terms of GDMT and device consideration for patients with intermittent LBBB (QRS duration exceeding 150ms) and HFrEF?

Besides HR variability how can we explain resolution of the intermittent LBBB with HF GDMT (especially with ARNI use)?

I would not consider an intermittent left bundle as criteria for BiV pacing. I would actually not consider it in my assessment of heart failure gdmt or device therapy in isolation, whatsoever.
