I feel fine so I am not sure if this is a measuring error with the watch or is really happening to my heart. I never get any low heart rate notifications but I think you only get those if your heart rate is consistently low for 10 minutes.
Several days a week my heart range shows a low of 40bpm. The time it records the 40bpm could be any time when I am awake 8am, noon, 6pm, 10pm. I haven't noticed it being recorded while I am asleep. I have attached a photo of my heart measurements from Sunday at 6pm till 7pm. The measurements were 70-75bpm but then one outlier is only 40bpm.
Does anyone else have blips like this on their heart data? I had a medical recently where they checked for atrial fibrillation for 1 minute and it didn't find anything. Do you think this is an Apple measurement issue? I always wear the watch tight on my wrist. I don't want to waste my GPs time of it is a regular Apple issue.
