I 'upgraded' (I use the term loosely, bc I had a Versa 2 before and loved it but needed the extra heart health features that are in the Sense) to the Sense 2 shortly after it launched.
I've had a few SVT episodes and wanted more heart features to keep better track of my heart rate, especially when exercising or having an SVT episode.
Most of my episodes happened when I had my versa 2 and my hr was pretty accurate to what it felt like in my chest (up in the 220s BPM).
In Dec I had a similar episode to the one I had in October (versa 2 was spot on my hr), and my sense 2 was not accurate at all! During the 45 minutes of my heart rate being 160 to 223 bpm (checked using a KardiaMobile EKG device to get a record of my Episode to show my cardiologists), and my sense 2 watch showed a wide range of BPM of mostly 90 to 136 and at one point it showed my HR was like 68 bpm (when it was actually in the 190s BPM).
I got the sense 2 to help me track my HR better, and it only seems to be accurate when I'm asleep.
I've contacted support, and they weren't any help. I told them I think my watch may be defective, and they told me to screenshot my app the next time I think it's not accurate (which I have screenshots already), wear the original band (which i explained doesn't fit - it's either too loose or too tight to be effective) or wear my watch on my dominant wrist instead.
Does anyone know if the Charge 5 is more accurate on heart rate? Or would the original Sense be a better option? Since I doubt Fitbit would be willing to replace my current sense 2 (that I bought directly from them in November after it launched).
I have an Android phone, moto g stylus 2021 (which I also used with the versa 2 I had for 2 years before getting the sense 2 last Nov).
