I have this problem for the last 10-15 days with my fr 245. Wrist heart rate suddenly goes up to 170’s while i am sitting for a few minutes then comes back to 60-70. I check my pulse, there is nothing unusual. I wear the watch as i have been wearing for months, so location of the watch on my wrist can not be the cause. I had the same problem with 4.00 sw. i uploaded 4.10 to see if solves the problem. But i am still having the same problem. Funny thing, connect takes it as an intense training and it completes my weekly intense work outs with false abnormal heart rate minutes.
Anyone has same problem? Do you think i must visit garmin service?
