There should be no problem with a pacemaker. In the days
before levodopa (i.e. treatment before we had Sinemet and Madopar), preparations
included a dopa-decarboxylase inhibitor there were some potential problems, but
not now. There is no problem with dopamine agonists either. When treatment for
depression is also required, the cardiologist
may be wary of some antidepressant drugs, depending on the particular
cardiac condition you have. Actually fitting and managing the pacemaker should
cause no problems and cardiologists are well used to looking after people with other
illnesses in addition to their heart complaints.
