Versa heart rate accuracy concern

[Lorilee2020]

When I'm on the treadmill, the fitbit days my heart rate is 105 or so...I know it's adding 140 or 150. My heart rate can be 105 just when I'm working at the hospital! Very frustrating!

Hi @Lorilee2020, welcome to the Community Forums!

Thanks for bringing this to our attention. Heart-rate tracking can be affected by several factors including air temperature and device location on your arm. For more information about this, please check our help articles:

• How do I track heart rate with my Fitbit device?
• What factors can affect my heart-rate reading on my Fitbit device?

However, if your heart-rate tracker seems inaccurate after taking the recommendations into account, please reply with answers to the following questions so I can further investigate:

1. What were you doing when you noticed the problem? Is this only occurring when you're on the treadmill?
2. Were you wearing the Fitbit device particularly tight or loose?
3. What was the position of the Fitbit device on your wrist? 

I'll be waiting for your reply if further assistance is needed.

It's adding 140 or 150 and getting 105? That doesn't compute.

Are you walking or running and at what speed? What do you think your heart rate should be? And when working, what are you doing that takes your heart rate to 105?

Have you stepped off the treadmill onto the rails and manually taken your pulse? The old "count pulses for 15 seconds and times by four" routine?
