errrrrrrrrr I am wearing one for the next 3 weeks. yuck! anyway this thing has a thing if you feel something you push a button and it records what is going on at the time. it also records on it's own when it senses something. ok so sunday and today it goes off by itself. that to me is scarey. the tech always says well it is nothing to worry about. makes me afraid to go back on the 20th! well you know what? it is MY heart and it is scarey to ME when it goes off! waaaaaaaaa
