Dear Frontier X User Community,
After considerable deliberation and expert advice, we have decided to suppress the display of the value of QTc going forward for all our Users.
The QTc feature had been released in light of widespread Emergency use Authorisation for Hydroxychloroquine for prophylaxis against COVID-19 (a drug that prolongs…Read More

Agree a good move but shame to lose a metric. I note HRV has also been modified? Would say the device for all it’s sold as requires additional data even if bespoke to FF, like Peloton strive score. Else loses competitive edge in my opinion.

Afternoon Everyone! Just got delivery of my Frontier X. I’ve been playing with it this afternoon and I have a few things that do not look right on some of my ECG’s. Please see images below. Let me know your thoughts. Thanks Matt.

I had funny readings first go. Have you put water on the strap to help the signal? I did not do that first time.

Hello, I’m a retired cardiovascular safety pharmacologist. You are not wrong in your thinking, but exactly correct. The upper trace is, as you note, at a cycle length of ~ 1 sec (970 ms to be exact). The associated QT for the first and second beats on the upper trace are 433 ms each, exactly as you measured. You shouldn’t include beats associated…Read More

Thank you for the clarification. I was one of those folks. I wouldnt say I was overly worried but I focused on it enough to share with my primary care doc.
