  • How do you set the default to cycling? I only cycle and have to change it every time…ugh

    • I too wanted this and have achieved it.
      From what I understand the next activity you record inherits the last activity. So before you record you next activity change the activity type to cycling from then on every activity will inherit cycling.
      This usually defaults back to something else after an update so it not permanent.
      You should be able to…Read More

    • Hi Matt, The device defaults the activity type to the previously recorded activity type. You can follow the below steps to default it to cycling , going forward:-…Read More

  • Been having a lot of PVC’s lately. My doctor said they are benign…and my heart is structurally strong. I’m a competitive mountain bike racer and have noticed some strange behavior when monitoring my sleep.

    Wondering why my heart strain is dipping into dangerous levels during my sleep?

    • I would recommend you get a stress test. I am not a doctor, but your tracings look abnormal and your ST segment is raised – a lot..

    • Agree with kallseN that it’s worth further investigation. On the plus side a lot of athletes would get an abnormal ecg result based on voltage criteria – I have myself, several times. However your QRS wave is ba

    • …is mainly negative and the st segment warrants looking at.

    • …in fact looking at the overnight ecg as magnified as possible i would query long qt. Apparently the QT segment durations in males should be between 350-430 msecs and if >=450 msecs you should possibly get it ruled out as your QT segment durations seem to be consistent around 460-480 msecs. Currently my own heart strain reading seems to vary…Read More

    • ..and all the flag posts may be because of your low HR . Apparently the typical RR interval should be between 600-1200 msecs and because you are bradycardic yours is about 1300 msecs , so I suppose it depends on exactly what the x2 algorithm is checking. LAFB may also be worth ruling out as that seems to show similarities to your ECG ie T wave…Read More

    • …and just noticed on my own ecg during sleep, and mine also shows lots of flag post warnings in the couple of hours before I got up – and for a lot of that my HR was 45-46 bpm, so it may be the slow bradycardia sinus rhythm that’s triggering these. My heart strain did stay mainly in the blue /green during the night though.

  • Can anyone weigh in on my workout graph?

    • Looks very similar to the PVC’s that i occasionally get during exercise (see attached file) . What were you doing during this period , if you don’t mind me asking. PVCs tend to be more frequent as we get older, but in many cases can be benign. However if you have loads during an aerobic exercise eg running (eg > 10-15% other rhythm, then may be…Read More

    • You have some PVCs. Can you feel these in your chest when they happen? How many do you have per minute ? I want to say don’t worry about them but it’s more complicated than that so you should ask your doctor who will drill into family history and general health to assess risk.

    • PVCs are tricky, do you want to be treated for something that doesn’t give you symptoms? If you have sustained pvcs, one after the other >5 or 6 in a row, then consider treatment.
