Spurious HRM reading or HR?
This one's been bugging me for a few days. I have guestimated my max hr at 182, based on the highest that I've seen it during a hard effort. This weekend, during a hard effort in the middle of fairly intense ride I glanced down expecting something like 170 and was shocked to see instead 190. It climbed up a bit to 194, understandable due to sheer shock and a little fear. After a brief moment it settled down to around 168. I definitely hadn't been at a 100% effort, not all that deep into the red zone even. Just a sort of half-assed sprint.
I wrote it off to a spurious reading. But it did react to my reaction, and lasted for a good 5 or 6 seconds, so maybe it was the heart after all racing for no good reason. Either can happen. I know that no one can say which with any authority, but how often do you see spurious readings like that on a hr monitor? What's your best guess of the odds that it was one way or the other?
