Heart Rate is sometimes wildly inaccurate / too high during activities

[MichaelS111]

Hello - I've seen many threads on this topic with many "me too" comments going back several years.

During some activities, my Versa 2 shows my heart rate either consistently too high or intermittently spiking way too high (177 bpm during a light/moderate run, which is probably 30 to 40 bpm too high).

I've tried all the suggested fixes - location, tightness, factory reset, etc. I even got a replacement watch from Fitbit, which has the same issue. After updating the new watch to version 72.1.23 it seems that *sometimes* the HRM is accurate, but not consistently.

I'm tired of having to second-guess my watch ALL the time. Since I was willing to try a replacement watch I'm now out of the 45-day return window, stuck with a watch that doesn't work properly and no support from Fitbit.

I'm just venting mostly, and hoping someone else will see this and either offer a new suggestion or at least feel comforted that they are not crazy, and this product is simply not that good and doesn't work well.

My Charge 5 does the same thing. It's terribly frustrating.

Sinus tachycardia is when your body sends out electrical signals to make your heart beat faster. Hard exercise, anxiety, certain drugs, or a fever can spark it. When it happens for no clear reason, it's called inappropriate sinus tachycardia (IST). Your heart rate might shoot up with just a little movement or stress.

Thank you for the interesting info, I hadn't heard of this. However, I purchased a Garmin smartwatch after giving up on this one, and it is very accurate and does not show these spikes. I've even confirmed it using a chest strap HRM, so I'm pretty confident the readings from the fitbit were erroneous.
