I have been having heart palpitations , have had anECG done and all good waiting on the results of a heart monitor, my symptoms start out as sinus problems and a sore throat and then I feel like my chest , back and shoulders are fall of wind, my symptoms started after my dog pulled me through a door after visiting the vet, it was so forceful that I nearly fell over, also when the palpitations are strong I feel like collapsing, thank you
