Well, I have added another “ologist” to my list of specialists.  I saw a cardiologist yesterday (4/25/18) because of atrial flutter which had corrected on its own before the visit.  He was not too concerned and felt that chemo was the cause. I will start a low dose of flecanide for the next month.  In spite of my vast experience, expertise, wisdom, and good looks, I am still somewhat bewildered by the fact that one can swallow a pill and the heart settles down, or blood pressure lowers, or blood sugar goes down, or infection is controlled, or hair regrows.  It is indeed of grace and mercy that we live 2018 A.D.
