Heart cinditions from use of Aderall

I am  a 41 year old female with a  normal BP 110/70 (sometimes as low as 104/62  w/ a high pulse of 130-160. There really is no trigger to the increase in heart rate, I comes intermittently at times when I am doing nothing as well as at times when I have stress with anxiety and of course after I exercise. What concerns me is that my pulse rate regularly 80-90 will just sky rocket out of the blue for know reason as high as 160. At times I feel  small stabbing pains, like a needle in my heart, palpitations where I feel my heart beating in my ears. and check my pulse at 130-160 manually. Im not sure what this could be? This has been going on and off for over 2 years. Lately I have been experiencing  intermittent shortness of breath, fatigue, and leg muscle/ foot cramping, or spasms(not painful)
I have had completely normal lab work. so normal that the Dr. said I was abnormal.lol  CBC, CHEM 7, Thyroid panel, hormone panel, everything normal.

I am a mother of three and am active but do not  exercise on any regular basis at all! Please do not reply if you are going to tell me that is my problem:( I have never worked out in all my years). I am 5ft 6" 140 lbs  I am embarrassed to say I am a closet smoker. I smoke 1/2 pk a day.
I have committed to stop smoking And I want to start working out.
I think this problem could be due to the fact that I took the drug Adderal  for aprox. 10 years. I  stopped taking it recently after reading all the controversy and thinking of my health. I now take Strattera. I  know  this  is not a side effect of the new medication. Strattera is a non-amphetamine based ADD medication. Could this be caused by previous use of Aderall? 20mg 2-3 x dly for the past 10 years? I do not have insurance right now and am unable to afford tests at this point. I just want an honest opinion of what kind of damage I could have caused my heart and suggestions on how to help myself if Aderall could be a factor, or if it is something else?

I believe you should ask the cardiologist on this site this question.  It does not sound like an anxiety attack, more like a symptom with a physical cause that can probably be treated effectively with beta blockers, but that is for the cardiologist to say.....r..g
