Sorry for not providing updates for a day or so. Patty seems to have improved somewhat, although she still has some breathing struggles and spent much of yesterday battling nausea. She's also had some funny heart rhythms, which we hope are just a function of her heart acclimating to the new device.
We've tried to work in some walks, because her doctor thinks some of the breathing problems may relate to deconditioning. Keep your fingers crossed that she's on the mend.
