I’ve had an AICD discharge on a cervical RF. Never again. I always do bipolar if patient has AICD now. I’ve also seen a pacemaker inhibit while doing cervical RF, even though the grounding pad was on the opposite side. I do bipolar if above the umbilicus.
By the way, does anyone know of research on the lesion morphology with multiple simultaneous bipolar lesions? Everything I can find is just two needles, but I’ve wondered what happens when you have 4 sequential needles, like for a palisade. So you have + - + -, it wouldn’t make much sense for it to just make 2 blobs of ablated tissue since the current wouldn’t really know which probe it’s “paired” with.
