Interesting post although I can't help you with your specific question!

I am currently on Domperidone (Motilium) for Gastroparesis in conjunction with Peripheral Neuropathy - so ??? Autonomic Gastroparesis. However my Gastroenterologist wants to try me on Cisapride (Propulsid) which has been removed from global markets because of cardiac side effects but is attainable on special request. I have had an ECG done and depending on those results will commence (or not) on Cisapride next week when I see the GI specialist.

The Domperidone has helped the constant nausea significantly but the GI doc thinks that Cisapride may help me be able to eat solid food after six months of having had only a liquid diet.

So I guess my query is, if something cardiac happens to me in the future, how will I know if it is due to the meds or due to the Autonomic Neuropathy advancing?? Are you suggesting that rhythm problems are the main manifestation of Autonomic Neuropathy?
