How do people with arrythmia manage the problem that most bycicle heart rate monitor devices cannot measure accurately their heart rate?

  • What "SE" stands for?

  • "StackExchange". Regarding "non specialized devices", which kind of arrythmia, which devices and who told you it's well known?

    Yeah, this isn't really a good fit for bicycles. More a medical question. Voting to close.

  • It is not a medical question. I am talking for a cycler with atrial firbilation, so bycle-SE is the proper site for the question. Anyone with arrythmia knows very well that a non specialized device is easily fooled trying to measure heart rate in a person with any kind of arrythmia. That person needs a heart rate monitor device, such as "sigma", "garmin edge" etc which also measures speed, time, cadence, climb etc. I cannot explain it more.

1 Answer 1


I can't speak to the specifics of arrythmia, but I will challenge the presumption a HR monitor is needed at all. Its entirely possible to train well without gadgets. If you feel the need for a gadget, a power meter would give a majority of cyclists the same advantages, if no more, as a heart rate monitor.

At the elite level, some people now believe that power meter and speed/distance (for runners) supersede the need for heart rate monitors altogether, and many more are less extreme, believing that heart rate is still a useful tool to complement power meters, but not as important as power meters. Combining the two devices does give better results, but requires an awful lot of skill to analyze and understand the results and translate the information into better training outcomes. Much more skill than most individuals have, or want to be bothered with. This area is the domain of professional sports scientists and coaches and elite athletes where seconds over hours makes a difference.

  • On the other hand the evidence from elite or even club-level athletes doesn't have much to do with people new (or even returning) to cardio training, and needing to not overdo it or to be motivated to keep up to a certain level of effort (this may or may not be applicable in the OP's case, and there may be other research out there that is relevant). For those of us in between who are driven by curiosity, it provides a way of comparing different activities. After disagreeing about the applicability of your answer, +1 because to the best of my knoweldge it's correct.

  • The problem is that a powermeter can cost 10x what a heart monitor costs. It is a much bigger investment. For training with a heart monitor e.g. Using a Heart Rate Monitor (and a cadence and speedometer, but no power meter), how can I remain in Heart Rate Zone 3? Commented Dec 19, 2023 at 21:01
