Bought Garmin Vivosport watch because blurb on Garmin site said it recorded heart rate constantly. It does, but doesn't report on it as I would like. I have Arrythmia, may need a pacemaker, and am trying to track the ups and downs of my heart during rest, to discuss with cardio team. I can display the graph on screen in Garmin Connect, but can't export or print it. I can save lots of .fit files, but can't find out how to convert this data to comma delimited, xls, any other format. There are lots of heart patients like me, being encouraged to exercise, but scared of overdoing things, and I thought this was an ideal way of recording heart rate, but it isn't, as I can't do anything with the data. I can view one day at a time, but can't compare days or see records for a week. Not interested in cycling stats, or any other stats, just the heart rate.
