@Glomil , don't need to call your doctor, it's just the way Sense works. Tasks involving a lot of quick hand movements, like brushing teeths, washing hands or anything else, always cause these fake high heart rate values on Sense. If, at that time, you measure your HR with another accurate device, you'll see that at those times Sense HR values can spike up to twice the real heart rate.
I also have that on my Sense since the beginning.
