Question 167534
if the rate needs to be {{{139<=x<=157}}} while exercising......  since this is only a 10 second count , we need to divide each limit by 6 (60/10), in order to have the right pulse limits for 10 seconds.  139/6=23.16 and 157/6=26.16 ------------------------------------------------------------------>so  pulse needs to be between {{{23.16<=x<=26.16}}} beats for a 10 second count
