I live in Chicago area, also. Could you share the name/ group of your cardiologist who understands cancer treatment problems ? I, too, had the same chemo you mentioned and I am also in the AFib camp. So far my cardio work ups have been normal and I have maybe 10 AFib sessions a year. My current cardio did not feel I needed ablation, so I take metropol and have flecanaide as a pill in the purse to slow my tachy sessions. I just returned to Chicagoland after a ten year break in Bend, Oregon so I am getting started with new doctors. I now go to a Mayo oncologist for my new LCIS ( 2003 IDC w/ nodes). Thx
