[|Human|] My uncle is 92 years old, never been sick, and has all of his faculties.  Recently he has been having "episodes" where he becomes light headed and has even passed out for a time.  Doctors are monitoring his heart medication and thinking about a pacemaker.  Is he too old to consider this?
[|AI|]  Hello, Welcome to Chat Doctor. I can certainly understand your concern. I have worked through your query in detail. Pacemaker can be considered in your grandfathers case. His age is not an absolute contraindication for a pacemaker. Infact a pacemaker implantation performed by an experienced operator is a safe procedure for patients of advanced age. The patients who are above 70 years old may have less complication rates than the younger patients according to various scientific articles in various studies.Hence, you can go ahead with your doctors opinion and advise. Complete cardiac evaluation is required before implantation of a cardiac pacemaker.It's advisable to take an expert opinion from an interventional cardiologist before going for the procedure. Please check with your physician if he shares my view and if you can prescribe these medications to you. Post your further queries if any. Thank you
