Not feeling "oomph" while running
My first post and thankful I found this club/forum. I had a PM implanted in late September 2019 due to syncope/heart rate pauses. I had two quite serious incidences and some episodes in between the two; after the second serious incident I had the PM implanted within 24 hours, so I didn't really have much time to "take in" everything that was happening. There is some neurological relationship to everything which is still being looked into, but at the moment, I am dealing more with maybe my settings not being optimal, which is frustrating. I do have an interoggation and follow-up after scheduled.
I am a runner who is training for a marathon and running between 44-50+ miles a week and having problems with speedwork runs and running hills. This isn't my first marathon and actually I ran a marathon in early November 2019 after my implantation. I even felt in better shape in November but I also was not running 50 miles per week at that point due to tapering for the marathon and then recovery after. Before this incident which led to the PM, my fitness was quite good and I suppose it still is, but I am not feeling any oomph when trying to complete speedier workouts and hill work.
Could this be due to PM settings? I have not been interrogated since October 2019 and I am right about in the middle of my training cycle (marathon is in late April). I believe my PM is set at 40/170 bpm. My stress tests reveal that I have problems with my heart rate/bp increasing with exercise (unsure exactly how much of a problem...that info was not really made known to me...yet anyway), so I guess it's hard for me to know if my heart rate is even reaching near 170 bpm. I did not have problems with this prior to my PM...I felt that speedwork and hills weren't a problem as my fitness got better. I guess there could be some other things going on and not the PM, but if anyone can provide any insight or has any experience with this that they would like to share/advise, that would be great.
