Hi I am on medication for HBP and keep well with it. I wear a garmin watch which records my heart rate, and it it usually around 60-70's occasionally dipping as low as 47, i have had my rate checked at the doctors and i have then checked the watch and they are both the same. I have been painting recently and have noticed its been going through the roof as I'm painting. My watch is worn on the wrist of the hand that is doing all the paint work, its an outside fence so its long brush strokes, its sitting about 179 throughout the duration of painting, only settling down when I've stopped. Is it just the watch, or the activity? I run on a fairly regular basis and it usually sits at 140 then?
