Fun story to add: I can't get my heart rate measured. I get so nervous about it that I immediately double my heart rate. Of course it's impossible to communicate that with doctors. One even equipped me with a 24h heart monitor. Only to have my stupid brain go on overdrive and clock my heart at 120+ for the entire time, with 0 sleep. I literally fainted when getting ekg cables on me. I now have on record a heart condition without having one: I just get nervous from measurements lol

It's jokingly called 'white coat syndrome'. Any doctor who has a clue should understand this.
