  • My HRV seems to be very low – about 4ms on average. I am fit and healthy and do mainly cycling – just done 4 hours at 185W output which I think is decent fitness.

    • Hi Nick, apologies if you already know this .. but the way hrv is mathematically calculated means that there is an inverse (but non linear) relationship between HR and HRV – i.e. it’s quite normal for HRV to go down when you exercise and up when you are resting – just on the basis of the fact that your underlying heart rate is higher in teh former…Read More

  • Having to get an Angiogram on Thursday to determine why my heart is failing. They can’t determine what’s causing the EF to be at 35-38% with no structural abnormalities, scarring, or valvular issues.

    Hope it can be fixed.

      Thank you for reaching out.

      You can find information in the following link:

      Can you share an ECG stream for a full workout or is it just the first 3 minutes?

      Please let me know if you need any further assistance!
