Hello, I am 34 female. I had ASD device closure 9 years back, last month I had an attack of tachycardia for 30 mnts. Next day I had done my ECHO, ecg Blood tests (lipid profile), all seem to be normal cardiologist suggested me to take met xl 12.5 mg twice and he said he will do holter in next month. I also suffer from palpitations almost regularly I take medicine for hypothyroid. I am very scared particularly of heart attack & I have very frequent episodes of general discomforts. Abdominal disturbances problem is, even with any slight discomfort in my chest, arm or any where, I got very scared, particularly of heart attack & I have very frequent episodes of general discomforts. Abdominal disturbances also occur with other discomforts (like dull ,sometimes sharp but point specific pain in chest for 5-6 secs, point specific pain in left arm). Can these pain & discomfort be heart related? Now I have a feeling that my doctors are not taking my concern seriously. My life is getting miserable.
