The thing is, I don't feel any different when this is supposedly going on.
I am wondering:
Is this some kind of reading error of the watch?
Is this normal when you are building distance and pace and pushing yourself
Is this atrial fibrillation?
Any thoughts or experiences would be greatly appreciated.
Thanks
Afib will potentially show up as a high HR reading but you will usually have other symptoms. If you're still able to ride a a moderate to high intensity then I wouldn't suspect Afib. I've had erratically high HR due to static when riding in dry conditions with a loose jersey. Usually happens at the beginning of a ride before I start to sweat.
Does the high HR match up with a harder effort or does it go up when you are just riding normally? What is your normal avg HR for the complete ride?
