Have had my pulmonary rehab assessment and after a long chat about my health was told. "Your results are too good to be copd, in my opinion you have exercise induced asthma. As you have palpitations you be gp should check out the heart as that may cause you to be short of breath." So now back to the gp. I do have a slight heart murmer but it hasn't been checked since 2005 . Feeling even more confused.
