To begin, I am 23-years-old and have been diagnosed with hypothyroidism and iron deficient anemia. A couple of years ago I noticed that my heart occasionally skipped a few beats. At the hospital I was given a chest x-ray, EKG, and 24-hour holter monitor, all of which came back normal. The symptoms subsided, but I do occasionally notice a skipped-beat or two around the time of my menstrual cycle. Is there a connection?
