Please forgive any typos as I am writing on a phone. My mother took me to a gov hospital here in Hong Kong after I'd complained for weeks abt chest pain. They've done an electrocardiogram, an ECG, chest x ray n now they want to do a holter which means another 2 days at the hosp as Mon. here is a public hol... my Q is, are Holters even accurate? My symptoms are basically all the OI and mitral valve prolapse symptoms that Dr Enlander said I had a year ago but I never did any tests. Anyone here w cardiac symptoms who were "cleared" by a Holter? Thamk u so much. P.S. altho I can't leave for 4 days, my mother took me here bc it is free.
