I am hoping you can tell me whether ectopic beats are excluded from the average value given for HRV? I can see that HRV is higher for me in strips where an ectopic is evident though I do have other occasional high values where I have no ectopics. I think that ectopics are causing me to see a higher score than perhaps expected.

I have observed that my cardiac strain is rarely zero, even when at rest. On checking while asleep recently, my strain varied between 0.01 and 0.03. Is this likely to be significant from a cardiovascular perspective?

It is very normal to have a small amount of variation in cardiac strain at rest. Cardiac strain is significant only if the value is greater than 0.1 mV, and the value of Cardiac Strain should be interpreted with context of what you were feeling at the time when the Cardiac Strain was high. So we wanted to ask you- did you have any heart symptoms…Read More

As a healthy female amateur cyclist in my early 60s my cardiac strain is usually around 0.12 max and 0.06 average over distances of around 50km cycle and on occasion close to 100km. I have no discomfort cycling and the summary indicates that the average strain is minimal. The max strain measurements of 1.2 are short lived and look like a small…Read More

Occasional spikes are very unlikely to be significant, especially if they’re not associated with any symptoms like chest pain, breathlessness palpitations, dizziness or unusual fatigue. A simple way to check this on a ride is to set a CS upper limit alert at 0.18mv, and only modify your exercise intensity if you get 3 buzzes in a row, or if you…Read More

Hi Amo, Ectopic beats are not excluded during the calculation of HRV currently. This can result in higher values of HRV in those sessions with ectopic beats.
