In a recent thread Stylianos posted a Youtube clip https://youtu.be/7-u8VTmeDF0 in which the author examined the heart rate measurement performance of the Sense compared to the Polar halter monitor. Which was very interesting, and thanks to Stylianos for posting that, but what I found particularly interesting was that the Sense was reasonably consistent with the Polar at lower rates, e.g. below around 100bpm as I recall. Now I am finding that in this range my Sense is measuring too high by about 20bpm, an effect also found by another poster here, Penniopolis. Given that the software in each watch is exactly the same this suggests a hardware issue. I wondered if any other owners have had the same experience, or is everyone getting reasonably consistent results. I should add that measuring the heart rate on my pulse oximeter indicates that the Sense is measuring high.
Well, the ECG app is FDA approved. So, at least there, I would think that the beats per minute is correct. If the BPM was wrong, the ECG would be wrong.
At least that's my thinking. I doubt the FDA would approve the ECG app if the BPM was not right.
I agree that I would expect the Sense's ecg measurement of beats per minute to be correct, and from looking at the results I think it is. However, that's using the heart's electrical impulses, which I think is what the Polar holter uses, whereas the Sense's displayed heart rate works on blood flow on the wrist. And that's the one that seems high to me.
Correct. When you run the ECG app the optical heart rate stops working. The green light stops blinking. It's the only time that the heart rate reading is accurate.
