Minimum HR on Charge 6 - Can it go below 38bpm?

[SlowAndLow]

I have bradycardia and have had several daytime ECG readings of 36bpm at the doctor. My older Garmin FR 235 tells me my HR during the day gets to 34 to 37bpm quite frequently and down to 30bpm at night. My Charge 6 has never gone below 38bpm and the graphs almost look like 38 is the minimum it would read as the fluctuates above 38 but flat lines at 38. Is there a minimum HR that the Charge 6 will read? I have both devices on now and they give different readings.

Hello @SlowAndLow and welcome to the Community.  Fitbit doesn't list the current specifications, although an older document said the range was 30-220.  I don't know if Support has the answer or not.

My Sense 2 has a screen not available on the Charge series.  It is a detailed heart rate for the last two hours.  I know my Sense 2 can go down to 36.
