fitbit 150 billion hours of heart data reveal secrets about our health


Really interesting - thanks for sharing. Here’s the link

My resting heartrate was around 67 and when I was put on a higher dose of heart drugs it went down to 57 (My Fitbit said I was very fit for my age 😂). After my ablation it went up to 75, then, because my drugs were increased again and Digoxin added it’s now down to 68.
Mmmm... I have several comments on the article. Interesting as I always am about this sort of use of technology. One sentence stands out for me Note, too, that this data comes only from people who own Fitbits — who are affluent enough, and health-conscious enough, to make that purchase. It’s not the whole world.)
Secondly - yesterday at Patient Day we were told NOT to trust our devices for measuring HR if we have or are in AF.
With that proviso - interesting.
I probably wouldn’t have bought one - mine was a birthday gift from my super healthy & fit daughter. I certainly don’t trust it for accurate HR readings, especially when in AFib but the trends are interesting. I like the sleep monitoring and exercise tracking.
Yes - since I got a Fitbit, I've found my resting heart rate to be an interesting indicator of my mental and physical well-being. A Fitbit might not give an accurate figure for someone like me in permanent AF but I think it does give trends reasonably reliably. For example, during a recent cold, my RHR went from 63 to 68.
I guess it might not be quite so responsive now I have a pacemaker stopping my heart rate from going too low!
Perhaps the big take away from this massive data sample is:
The link between body mass index and resting heartrate. I understand that a lot of people don't like the concept of BMI but this report identifies the link quite clearly.
Assuming that you accept the resting heart rate as a measure of fitness, the low amount of exercise needed to make a difference to your resting heart rate.
