Obviously some riders never go near their true HR max, but I doubt that you are in that category.
When you hit your new 200+ peak, does it come back down like normal when you back off or stay very high for any length of time. Are all your other HR zones unaltered?
It comes right back down immediately. I stay away from hitting the 200 area. Hit 192 and even that was too much. These day’s hitting the 180s is easy on hard climbs but again the HR comes right back down.
Appreciate the concern, and will bring up the anomaly with my cardiologist. Cheers
