*Would like to share my experience For past couple of days I am going through dizziness , chest pain , flutter , palpitations kind of issues. Many doctors , tests are performed and everything came back as normal. They marked it as Anxiety disorders and asked me not to worry about it. Few weeks back I was checking my sleeping heart rate variations and I was surprised apple watch told me High Heart Rate for almost 1 hour during deep sleep. It happened 4 times where I never realized something like that happened in sleep and was scared. Thankfully my cardiologist gave me Heart Event monitor for 1 month and yesterday was the night where apple watch said my heart rate readings were jumped from 64 to 109 and they were between 109 to 125 for almost 45 minutes. I was so surprised to see Event monitor readings during this period were still 60-65 range.. Conclusion : Incorrect apple watch readings were one of the trigger point for my anxiety....*
