Four years in
So I'm four plus years into my first PM, Biotronik Eluna-DDR. My doc recommended it because of the rate reponsiveness of the Biotronik technology, CLS, since I am a very active 73 year old (Jogging, gym, skiing). Things have gone pretty well. Each year I push the doc to up my top rate because I seem to (according to my HR watch) be pushing against the upper limit. When running, for example, I run out of oxygen before my legs get tired. Started at 120, now up to 150. Last time I saw him he balked at going beyond 150.(I asked for 160) Said he would increase the responsiveness to see if that helped, but I really don't see much difference. He also made a vague comment about CLS not really performing as well as hoped. Any other comments on this?
One other thing that I do note: I can run a fairly long distance (3 miles at but when I am doing chores that require moderate upper body exertion, I get out of breath fairly quickly. Not sure why. Others have this experience?
