  • 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….
