I have had my pacemaker for 2 years now and no problems. My heart rate started to increase last month from 70 to 80HR. The Dr. said I have AFib now. He hasn't reccomended any changes to my meds, Just come back in 6 months for device check, Echocardiogram and Dr. visit. Does any else have this problem? Evidently AFib is here to stay. I am 81 so thats on the downhill slide!! I take good care of myself, good weight, exercise daily and have a good life. I have noticed that I am more anxious and depressed lately. I do have one glass of wine most days, info I just read said to discontinue wine (ouch). Maybe not as have already given up most deserts. Any suggestions?
