It sounds like you husband has had quite a confusing journey with his Parkinson’s medication and I’m truly sorry to hear about the Ventricular tachycardia/ bradycardia that he suffered. The progression of his symptoms must be incredibly hard for you both.
Parkinson’s can cause problems with your feet and in particular, people with Parkinson’s can sometimes experience foot dystonia like your husband. I would encourage you to visit a podiatrist or a chiropodist for advice – there is no difference between them. However, you may want to first visit the Parkinson’s UK website for more information on this here: Foot care | Parkinson's UK
Members of the community have already shared their experiences with managing foot dystonia and I have listed a few threads that you may find helpful:
