Pacemaker's effect on VO2 max and value of workout heart rate data
The current settings on my pacemaker are 60 and 165. I recently had a very good effort on my bike and my Training Peaks software gave me a Threshold heart rate of 161. i understand by definition Threshold Heart Rate is 80 to 90 percent of your max heart rate.... and the VO2 bit for me is that my Garmin Software gives me a VO2 max value of 43/44.. Which fo a 69 year old is decent...
... So the question: Is my pacemaker causing my VO2 max to be understated or overstated?
For training purposes i would like to know what i am dealing with. From the Threshold HR value i surmise my calculated max heart rate is roughly between 170 and 200 so in my workouts i effectivey have a no data zone above 165. I know something is going on as my percieved exertion will vary on my harder efforts within that zone and i suspect my heart is capable of a higher rate. I have thought of lying to one of my platforms, probably Garmin, with a range of 45 to 180 and see what happens. For right now though i know how to go fairly hard on my workouts but i find my HR data unreliable for things like when to back off or take a rest day. I want to improve but under current settings it's like i am going at max effort all the time and i don't think that is right.
I have had my pacemaker for almost 2 years now and have had several adjustment to my high end from 130 to now 165 and have come a long way in my abilities. I am eternaly greatful for that as i am able to ride close to what i was doing 20 years ago, so if this is as good as it gets i would be ok with that.
Any and all advice would be appreciated.

I'm 43 and have had my pacemaker four weeks today. I'm looking forward to living another 50 years and this marvelous device inside me will help me do that.
