Specifically I would like to be able to track how many times I go over my max hr per day, does anyone have any ideas or suggestion how I can do this?
@alice111 I'm not at all familiar with the Fitbit. But, I do have a Timex HR monitor watch with chest strap. It can be programmed with an "in zone" range. The typical method for calculating the top of the range is 220 minus age, multiplied by anywhere from 50 - 70 percent, depending on how impaired/sedentary you are. For myself, I've set the upper limit at 65 percent. If not using a percentage calculation, I believe 110 bpm is the maximum suggested for ME patients, at least to start with.
My HR monitor doesn't track the number of times I go over my max; but rather, the total time recorded (which involves starting the chronometer), and the length of time "in zone". From this, it is easy to calculate the time "out of zone". The lower figure is also important, because having a HR that goes below your "low" will also be considered as being out of your zone. For this reason, my bottom for the zone is set at an otherwise unnecessarily low "40".
The figures that my monitor records are: "Total Time" and "In Zone" (hours and minutes), "Minimum", "Peak", and "Average" (bpm). Some days I let the chronometer run/record all day, which can be helpful in seeing the trend. Other days I start/stop recording before and after a specific type of activity to establish how specific tasks (eg. cognitive vs physical, sitting vs standing) affect my HR. I'm learning a tremendous amount, but it is rather discouraging to see how effort that would barely register for a healthy person has such a dramatic effect on me.
I've been recording consistently for more than two months, so have lots of data for my husband to input in a computer spreadsheet he's developing, with graphing options. Of course, the Mio is probably more sophisticated, and may have an App that does this for you. However, my experience is that these devices are intended for an entirely different purpose than the "pacing/activity management" most ME patients use them for. The pre-set HR target zones don't apply to us, so you may need to figure out a "work-around" to get the statistics you need.
Good luck -- I hope this opportunity provides valuable insight.
