I just got a report back that my heart has extra beats. The only thing I take is levoxyl. I'm 60, female, not over weight, don't excercise but have a lot of stress at this time, don't smoke (quit 9 yrs. ago). I think in pretty good shape for my age. What does this mean and should I go to a cardiologist? I started a low dose aspirin about a month ago because my heart seemed to be beating faster or harder for a second or two at times, not often.
