I am a white male 72. Have a pace maker for 2 yrs now (my Dad died at 52 from congestive heart failure) I had my pacemaker set up from 60 to 70 as I was having period of "functional black outs" (driving on a road never traveled, but wake up 15 miles down the narrow and curving road) I am beginning to have these sensations again, plus weight and swelling, but exercise 3 time a week. Afraid to tell my doctor, as I live in the country, alone.
