Update on new pacemaker settings
I have 2nd Degree AV heart block.
It has been a week since I have moved from minimal pacing (13%) set at VVI40 (my ventricles will not beat any less than 40bpm) to DDD 100% pacing.
My heart thuds stopped immediately. The long wait before pacing (1.5 seconds on blocked beats) is now gone. So that is really good.
I feel a little less fatigued but not a step change so let's see how that progresses.
Exercise is more complicated. I have now done three runs at these new settings. When I ran hard on VVI40 settings I would get to to 180ish bpm but almost certainly would have ben skipping beats. Running was much harder and I am about 20% slower than normal (normal being before bmy heart block started in 2020)
the three runs on DDD and full pacing are definitely showing that my heart rate is not reaching 180bpm on these harder runs. I have got to about 150ish.
I find this fascinating. I do not have any issues with my natural pacemaker yet only a few days after this setting my heart rate does not seem to need to climb to 180bpm for the same efforts.
This has got me pondering, has my high heart rate in the past been compensating for my heart block and I just did not know it?
In other words beats were being missed so my heart rate increased to meet the demand. if so I am expecting that once these new settings have bedded in I may notice my heart does not need to work as hard for the same effort.
Any thoughts on my logic?

You run like the bionic man.
I can bike a 40-50 tour with no trouble.
