On a recent walk, at a steady pace, I noticed my fitbit was recording my pulse rate as >160. This seemed really odd as, while my pulse was going at a decent rate, it was no way near these kinds of numbers. This has happened a number of times and I'm wondering what the reason could be.
I've come up with the following options:
1. Ectopics - even if I haven't noticed them, could these have been confusing the Fitbit such that it records a much higher pulse rate?
2. Short runs of AF (would I not have noticed?)
3. Short runs of ventricular tachycardia (would I not feel this?)
I'm a bit perplexed as I haven't felt anything wrong while walking, but since my cardiologist recommended that I keep my heart/pulse rate low (ideally below 110bpm) I'd like to know whether others have experienced dodgy pulse rate monitoring by their fitbits and if they have worked out the cause.
Thanks in advance,
