Still off of the pacemaker, J.J.'s been sleeping soundly since rounds. Sounds like they will leave the wires in for a while. When they're comfortable that he doesn't need it they'll likely snip them and leave the wires in his body. They're stainless steel covered in plastic. Hopefully not a lame grade of plastic that leaches nasty stuff, but it's not like he doesn't have a lot of other foreign objects in his body! Cloth conduit, bovine valve, cloth patches, metal stent (like chicken wire) and his chest bone is wired together.... Apparently it's really common to leave pacer wires in, other centres do that routinely. They don't want to pull them out and cause bleeding because they're removing the chest drainage tubes.
