Cardiology visit

I went to the cardiologist today for a cardiology consult as to why I am having these palpatations that did not go away when the Anemia became controlled.
The doc went over the test results from all the testing that was done just before my hysterectomy and decided to put me on a heart medication called Atenolol to control the palpatations and also decided to do more testing. I will find out Monday when I have what is called a Dobutamine Stress Echo done at the hospital. I hope that this test comes back fine. He went on to say that if it shows abnormal, he wants to schedule a Heart Catheterization.
I am upset at the fact that these palpatations did not go away when my anemia went away. I was hoping that my own doc was correct when I started having these problems and went to the ER last month. I guess it's good that we find this all out now and I take care of it early on in my life instead of fiding out due to a heart attack or something. Who knows if my mom had these problems and just dismissed them and that led to her death at such an early age?? All I know is that I want to live and watch my son grow and perhaps find the love of my life to grow old with....that would be nice.
I have also committed myself to get even more healthy then first anticipated a few months ago. I have always been health conscious, but I am now more than ever. I don't want to die at a young age of a heart realated illness, like other family members. I have decided it will not get me.
