hello there im due to have a 24 hour ecg monitor this thursday would like to know if the machine they use picks up if its just stress , iv been getting constant palpitations for a few months now they dont stop one after the other all day and sometimes all evening and then stopp for a few weeks then the same again , the thing is they have just started again after not having any for about 3 weeks and im worried im still going to have them when i have the monitor on thursday , now i know the palpitations are the reason im having it anyway but i really would of prefered to have it while im not having the palpitations it might sound silly but its really stressing me out , so when i go back to have it looked at will they know if the palpitations are down to stress or not because they dont stop once they start and im worried there is something wrong with my heart . thanks
