Closed Loop System
I am 57 and just had a Biotronik Edora 8 DR-T implanted on Oct 11th, 2019. I am very active and was enjoying running, biking and swimming when all of this unfolded. It all started about a year ago when on a run I felt like I was going to pass out. My legs felt like they were encased in concrete and I had a feeling of impending doom. At first, it only happened when I ran, but then started happening when I swam. It was intermittent for a few months but then in September, it began to happen more and more often until I went to my doctor. One thing led to another and here I am with a pacemaker and still having trouble.
I took the first week off from surgery to recover and then on the second week I began to run again. I went from running 2 miles and feeling like junk to 10 miles a week and feeling pretty good. On week 4 I went out for a run and felt like junk again. It felt just like it did before the PC and I began to wonder if the leads came out. I went to my doctor and he assured me the PM was working fine. However, he adjusted the unit to give a better range, but this did not help, so I went back again and he switched it to the "Closed Loop System". That was 2 days ago and I have not yet tried running because my unit randomly goes up to 140 bpm (as measured on a pulse oximeter). It has been all over the place for the past two days, getting down as low as 49, up to 140 and usually around 88-110. He prescribed Metoprolol Succ ER 25mg as a beta-blocker to presumably lower my pulse, but it does not seem to make a difference.
Does anyone know if this is normal to prescribe a Beta-blocker for this reason? Does anyone know how long it takes for it to be effective? I am having a hard time not being able to work out the way I use to. Does anyone else have a similar experience?
