My Alta HR has always been fairly accurate in the heart rate reading. Three days ago it read high on average all day, but I figured I had been working hard in the yard and didn't think much of it. Two days ago I had some very high random spikes, but again this happens once in a while and I just dismissed it. Yesterday my readings were normal until about noon and then I had random spikes up to 164 during the day -including a walk where I apparently reached 166bpm and I usually reach 120 at the most-and then a sustained 188 for 2.5 hours in the evening (I was basically relaxing during the whole time, no exercising!). Unfortunately I didn't sync it until this morning so I didn't realize it was reading that way to manually check (although I felt completely fine all evening). Today I have reset my fitbit, and shut off heart rate and turned it back on. I also contacted customer service chat and had to do this a second time. When I put my fitbit back on from the reset it read 174 and since then has jumped to 145 (when I manually checked it was in the 90s). Has anyone else had this happen to their Alta HR? Is there a way for me to fix it? Or is it just time for me to replace?
