He has an intern/fellow /whatever that does most of the talking and was very helpful. I was at the main
Mayo Clinic in Rochester, MN, about 2 hours south
of the Twin Cities. I know they also have clinics in AZ and FL(?) but I think they are smaller.
I think you start out in general cardiology, however, and then cardiology checks you and out refers you to heart rhythm. Good luck, let me know if you end up making an appt there - they are the best!
