Random high and low spikes on my IWatch 4 heart rate monitor.
My watch has recently been recording random high and low spike on my heart rate. It will say 41(which I actually checked with my radial artery) and I was actually 84. It will record 39 and then jump to 160. I know my heart is not beating irregularly like this. Is there anything I can do to correct this. Thanks so much.
