Maintaining my heart muscles Ejection Fraction and Condition
Hi, this is my 3rd post to this forum. I am very pleased that this site even exists and I have a lot of questions. I presently know enough about my PM to be dangerous, lol.
From my earlier posts you will see that I received what I think (not certain) is a Dual Chamber PM roughly 3 weeks ago. It is a Saint Jude PM.
With the holidays and all the confusion, I haven't had much time to analyze my situation. I know I feel a lot better than I did before in many ways and I thought I felt good before. So I am very thankful. Being in that cardiac unit for 3 days, 3 weeks ago came out of the blue and was quite sobering.
Exercise, particularly swimming, is very important to me. Over the last 5-6 years, I transitioned from running 5-8 miles a day to swimming 1-2 miles a day 4 to 5 days a week. I am not a Masters Swimmer, I just enjoy swimming as a way to stay in shape and maintain a positive attitude.
My question is this, my Ejection Fraction at the time my PM was implanted 3 weeks ago was 65%. I had never heard of an Ejection Fraction before and I was told this was good. After a little reading I have learned that some people experience a deterioration in their Ejection Fraction after the implantation of a Dual Chamber PM. Does anyone know how likely that possibility maybe vs the possibility of my maintaining my current Ejection Fraction, or improving it?
Also, if I continue to exercise, can that preserve my Ejection Fraction going forward, or might exercise cause it to decline given my Dual Chamber PM's involvement. Should I explore the possibility of a Bi Ventricular PM?
I would greatly appreciate any input other athletes might have regarding the questions I asked, or pertaining to questions I didn't ask but should have. Thank you.
