Welsh woman living in SW England here. Have POTS, EDS III and vasovagal syncope. Everything seemed to sort of be in balance , until Monday when I collapsed in the hospital whilst waiting for hubby to recover from eyelid surgery! Heart rate apparently dropped to 46 and BP to 86 - the advantages of having a crash team on site 😊 I take fludrocortisone, and until now it was largely keeping symptoms in check, so feeling a tad frustrated.
