My old Versa started registering high heart rates when I was walking, I thought maybe the battery was running low and it was only a year old, so I got a new one and same thing, I have compared it with O2 monitor and its showing up different and been to the doctor. How can I fix this problem ??
Registering rates 125 up to 158 and then dropping really fast. These are sometimes when I am just sitting.
