Subject: [ferrethealth] Re: Low blood sugar and irregular/low heart rate

Thanks, Sukie=85 that is exactly what they have diagnosed her with. She ha=
s a complete block (level 3). The cardiologist says that the only real tre=
atment for this would be a pacemaker, but that she isn't the best candidate=
considering her age and the insulinoma and adrenal disease. He also menti=
oned attempting treatment with theophyline, noting that it is not usually b=
eneficial. For now, we are focusing on stabilizing her bg. Any experienc=
e with this medication?
