How does the heart rate recording time unit of EDA scan? Using Charge 5

[Huiyeong]

Hello.

I am Huiyeong using fitbit charge5 for experiment of master degree. I have a question about the heart rate of the EDA scan function.

In the tab of my journey, I can see the variability of heart rate during eda scan. But I cannot know exactly how often seconds heart rate fluctuations are recorded. I think it was recorded about 70 times during an EDA scan for 3 minutes, but I'm curious because I can't know for sure.

So could I know how often seconds the heart rate is recorded in the EDA scan function? I could not find any mention of this topic in this community and Charge 5 User Manual, so I'm leaving a question.

Thank you.

Below picture is the variability of the heart rate in my journey tab.

Welcome back, @Huiyeong to the community!

Thanks for asking about the EDA scan using your Charge 5.

The EDA scan app tracks changes in heart rate and electrodermal responses—tiny electrical changes on your skin—so you can see how your body responds during mindfulness sessions. 

All Fitbit models, except a few older ones without any heart rate monitoring, do measure HR continuously whenever worn.

Thank you for replying to my question.
I knew that fitbit charge5 measures HR continuously whenever I worn and I can see the record in my journey tab.

However, what I was curious about was whether the numbers that are confirmed when I move and drag my finger along the heart rate waveform as shown in the attached photo above are recorded every few seconds.

When I did a rough count, it was 70 in 3 minutes.
Could you please give me a new answer on this?
Thank you and await your reply.
