Great to hear re arrhythmia and that they are noticed as artifact. Thanks for spreading the word about how common they can be. Folk may notice that increased ‘stress’ as monitored on HRV4 due to training can also be due to chronic or acute ANS activation and increase arrhythmia activity. Using the app is useful over time to take control of overactive sympathetic responses.

Thanks Marco!

I visited the reference on comparison of hr and hrv comparison and now am really confused. I have been using hrv4 for some time and use the iPhone camera measurement for 1 minute. I also have an Oura ring and tried importing its data a few times and after it failed to download a few times I went back to iPhone. I run daily with a Garmin FR965. I also have a Polar H10 strap as well as a polar arm band. I have settled on the arm band for every day running. Which should be the preferred method for hrv4. Also the article suggested that at least a 5 minute test was needed for best accuracy. How did the researchers evaluate the Oura ring. I am not aware that there is any other way than using overnight average? How do you suggest I measure my hrv?

My background. I’m an 80 yr old former marathoner. Who only runs 2miles every day. My program is a maintenance one which I think is fine for my age. The reason i have so many devices is I had trouble finding a device that would not give me crazy data on occasion. Gave up on running with Apple Watch. Garmin was good until it wasn’t. Garmin strap was not consistent so tried polar strap and eventually that gave me erroneous data. Have been using Polar Verity sense armband for several weeks and all is good. None of my inaccurate events had associated symptoms. When this stuff first happened I got an ekg which identified a left bundle branch block. I subsequently had echo and chemical stress echo and was told to keep doing what I am doing.

hello Conrad, I would use the verity for exercise as you do, and in the morning, I would either use the Polar H10 (make sure it's humid so that it provides good contact with the skin), or the phone camera, depending on what you find easier, but I would stick to the same method over time, for consistency.

Tried the polar h10 to see how it works and not save data. Hrv4 indicated that it did not record rr data only heart rate.
