  • I am still totally in the dark when it comes to using this date. I have used a Polar for 30 years. But I can’t decipher what to do with the tracings on Fourth Frontier. Where do we even start?

    • Probably need to read up on ECGs, but a bit like the Polar or any other previous generation of heart monitor, you don’t have to do anything with the data other than track. Some people like to have training programs based on various heart metrics.

  • Is the ECG able to test/time my PR interval?

  • A few days of using the device. Seems to work great. I’m a data nerd and would like to work with the detailed data in the ecg charts. I read on Twitter there was a raw interface for purchase for researchers, which (ahem) I am actively doing.

    Is there any information of this or do I need to contact FF directly?

  • Brand new here. Any assistance appreciated. Is there just one area or forum to post, or are there various chats based on subject matter? I have questions on the Heart Strain measurement and a few other things….

    • Hi Robert. I’m also new. My X2 arrived today. Interested to know if this is the right place or if there is somewhere else.
