Hi, just got my Frontier X and used it for my Tempo cycle into work. Happy with the data. Is it recommended to wear the device during rest (to possibly get a users baseline metrics) as well or only for exercise sessions?
Thanks Fidel Gonzalez

Hello, during runs (especially above 130-140bpm) I see high QTc values (>500ms) which is at the “Risk” region. Does “Risk” means that it it something that needs to be checked, or it is a normal calculation margin of error on high pulses? I dont know if anyone else see similar patterns.

I can’t view the other comment, but the QTc prolongation that you describe is very likely due to an under-correction for heart rate. QT is exquisitely rate-dependent and shortens as heart rate increases. However, due to the QT rate-dependence, a formula is used to approximate the QTc (QT corrected) at a reference heart rate, usually 60 bpm in…Read More

Guys! I have great use of my FX and are trying to get one of my best Friends to buy one.
He had, just sittning down Cardiac Strain 25 and HRV 3-8.
Is it possible to help him with an analyze on my account, it looks bad…

My first 3 mile run with the Frontier X. Fastest I’ve ever run it…
However, my Cardiac Strain was .02 … surely this isn’t right? particularly as;
my Heart Rate was 170bpm, Breathing Rate was 52pm and Body Shock was 154.
I’m not sure I can trust the Cardiac score…the AI claimed this was a moderate work out! yet…it was the hardest…Read More

The Cardiac Strain value can still be low and it just means that the heart is getting enough oxygen. However we need more context and need to look into data in depth to interpret it effectively. We are also making modifications to the language of the AI feedback and improving on it. Reach out to us on support@fourthfrontier.com if you have any…Read More

If your QT gets too long you could be at risk of arrhythmia. QTc is QT corrected for Heart rate, so if you’re getting that I’d definitely get it checked out, although there are individuals who have a slightly prolonged QTc for no apparent reason. Better be safe though.
