I’m at work. Have had to walk a couple of miles due to site visits. I’m horrendously unfit, fat, and when I get anxious my heart starts missing beats. I noticed a few whilst walking and I’m so close to going to A&E even though I know that would be stupid - I’ve had a lot of tests (health anxiety). Is it normal to miss a few beats whilst walking at a face pace? They didn’t get significantly worse.
