 [ Symptoms ] innocent heart murmur has started to give symptoms about 8 years ago i went to the gp with breathlessness following ecg is it was diagnosed as an innocent heart murmur i went back about 4 years ago with increased symptoms but they said that it was nothing over the last few years i have been having episodes of palpitations at least a few times a week until recently i had never fainted before but i have fainted 3 or 4 times alongside these palpitations is it worth going back to the gp i feel like i am going to be told its nothing again [ Disease ] go see a cardiologist and have a highly level heart examination by this specialist an ecg does not diagnose innocent murmurs a murmur is heard by a stethoscope and the determination of it being innocent is one made by the medical professional who is hearing it
