Endurance athletes frequently have a high normal A1c. I actually know some that have been treated for this. Chances are, you’re not pre-diabetic. Imperfect population health markers occasionally need more context. Full article on that sub thing below.

It’s only a matter of time but dual energy PFA/RF catheters will also transform VT ablation My N is 1 but it was a shocking 1 I’m still a slow adopter and medical conservative but we (EP) are at an inflection point in technology It’s good. Really good.

Combined RF/PFA for ischemic VT ( Anterior/anteroseptal scar/ apical aneurysm) @NorthernLightH The “ new” paradigm for ischemic VT ablation : - Ablate early - Minimize/avoid VT induction - Identify lines of block ( WADL/ILAM/Peak frequency..etc ) - Combined RF/PFA - Same…

I told a patient who was still on a lot of oxygen that we would let her eat when her O2 requirement was a bit lower. I asked her if she craved anything and she said, “pizza”. That evening my resident got her a pizza. That’s what I’m looking for in a young doctor. No one cares how…

This is bad news. This is very bad news. The US government has stopped the funding of PubMed, the most comprehensive database of biomedical literature. Why would you do this? This database it literally a matter of life and death.
